Table of Contents Biomechanics

Civil Engineering

Exponent’s biomechanics staff use engineering and biomedical science to explore the cause, nature, and severity of injuries as well as to address the interaction between the body and the physical environment. Staff consultants use medical records, testing, computer modeling, and extensive knowledge of human injury tolerance to determine whether an injury or claimed injury is consistent with a specific set of actions, an allegation of product defect, or exposure to a specific accident environment.

Exponent’s Civil Engineering practice provides broad expertise that includes geotechnical engineering, geological engineering, engineering geology, and geology to address a host of geo-failures, including landslides, foundation and retaining wall failures, dam and levee failures as well as earthwork construction claims. Our Water Resources staff specialize in the application of proven hydrologic, hydraulic, hydrodynamic, and sediment transport research and science to provide scientifically sound and cost-effective solutions to our clients.

In 2008, Exponent assisted an implant manufacturer in the evaluation of various state-of-the-art hip implant designs. These bone conserving implants were designed to provide an alternative treatment option to conventional total hip replacements in younger, more active patients. As part of this work, we developed computational (finite element) models of the femur to examine the biomechanical effects of implant length and the fit-and-fill of the devices. Exponent helped to establish the short term stability and load transfer capabilities of the implants. From this study, we determined that the use of certain bone conserving designs may be feasible from a biomechanical perspective.

In 2008, we continued to analyze the effects of natural disasters and broadened our services to the energy sector. We have analyzed a host of large and small landslides in Southern California. Noteworthy landslide investigations have included the La Conchita landslide and the La Jolla landslide. We have also expanded our services for the energy sector by evaluating the cause of foundation failures of a large ethanol production facility and providing analysis services for design of new nuclear reactors. Our hydrologists continue to address key issues in floodplain management such as delineation of flood hazards, and the identification of possible measures to mitigate potential impacts

Buildings & Structures Construction Consulting

The basic function of a building is to provide structurally sound, durable and environmentally controlled space to house and protect occupants and contents. If this basic function is not achieved, it is often because some aspect(s) of the building design or construction failed to perform the intended function. Exponent’s architects, engineers, and scientists have a broad range of expertise with such failures, and we provide clients with in-depth investigations of problems with building systems and components, including finding the best options for repairing the problem and mitigating the risk of future failures.

Exponent’s Construction Consulting practice provides risk management, project oversight, and dispute resolution services to help our clients manage the complexities inherent to large construction projects around the world. Our multi-disciplinary staff, which includes engineers, architects, scientists, cost accountants, and technical specialists, provide these services to both the public and private sectors. From a risk management perspective, Exponent’s construction professionals help anticipate problems and avoid pitfalls in cost, scheduling, and scope by improving the project control framework, conducting four-dimensional and probabilistic scheduling analyses, and performing comprehensive constructability reviews. The project oversight services team supports the project from the design and contract review phase, through project planning and procurement, and throughout the course of construction to project completion. Exponent’s dispute resolution services professionals assist clients in quantifying schedule delay or acceleration impacts, with cost and damages analysis, or in determining entitlement through claim resolution and project closeout.

During the past year, in addition to performing structural assessments of a variety of residential, commercial and industrial buildings, our engineers responded to the devastation of Hurricanes Ike and Gustav. Our evaluations included property inspections and engineering analysis of more than 150 buildings to assess the nature and extent of storm damage and develop repair recommendations. In addition to failure investigations, the Buildings and Structures practice has been performing engineering risk assessments for private owners and government entities to help them decide how best to prepare for catastrophic hazards such as hurricanes, earthquakes or terrorist attacks.

Table of Contents In 2008, Exponent’s Construction Consulting practice continued its efforts to expand in risk management and project oversight service areas, relying on its unique blend of construction and engineering professionals to help clients cut costs, increase efficiencies, and steer clear of potential project crises. Exponent’s construction consultants integrate into their work advanced construction scheduling techniques, including probabilistic and four-dimensional analysis, and conducted constructability reviews to help clients mitigate risk around ambitious projects in an uncertain economic environment. In addition, Exponent advises clients on the construction process by providing project monitoring expertise and implementing appropriate project controls that helped ensure timely execution and delivery of client goals within budget forecasts.

Electrical & Semiconductors Exponent continues to be a highly sought-after resource for understanding current and potential risks involving electrical and electronic components. Exponent’s team of electrical engineers performs a wide array of investigations ranging from electric power systems to semiconductor devices. We operate laboratories for testing both heavy equipment and light electronic equipment. Computers and specialized software are used to analyze electric power systems, circuits, and other equipment configurations. In 2008, our engineers continued to expand the scope of their intellectual property support services. This past year, the practice worked on multiple high profile complex patent and trade secret litigation cases in the district court system and the United States International Trade Commission. Services provided by our engineers included software source code review, electrical testing, over a million pages of technical document review, validity and infringement analysis, calculation of economic damages, and patent portfolio due-diligence analysis.

Ecological & Biological Sciences Exponent’s ecological scientists provide strategic support to clients on issues related to Natural Resources Damages (NRD), clean-up of hazardous waste sites, restoration of wetlands and other natural resources, large development projects, resource utilization (mineral mining, oil and gas, and wood pulp), and the use of chemicals and other products in commerce. The practice specializes on assessing the fate and effects of chemical, biological, and physical stressors on aquatic and terrestrial ecosystems. The practice is comprised of nationally-recognized experts that cover all disciplines related to the ecological implications and risks associated with these projects.

Engineering Management Consulting In late 2008, Exponent launched a new practice in Engineering Management Consulting. This practice provides multi-disciplinary expertise and rapid response to assist clients with technical and management consulting services, often in extremely short time frames. Our consultants provide services in the areas of asset strategy and planning, project management, engineering, construction, maintenance, operations, environmental and risk analysis. Staff have evaluated strategic options of generation assets and performed organizational assessments, root cause analyses and independent design reviews. Our consultants help organizations identify, map and improve their core business processes. We perform risk analysis ranging from compliance to total businessbased approaches and address a number of issues critical to the operation of a client’s facility.

During 2008, Exponent continued to provide expertise on NRD and remained one of the leading companies in the nation in this technical area. In addition, the Ecological and Biological Sciences practice, together with other practices, initiated several new efforts. These included a focus on the potential impacts of climate change on natural resources and on businesses and communities. This multidisciplinary initiative draws upon the expertise within several Exponent practices. Another multi-disciplinary initiative involves work for the utility industry on assessing the environmental and economic risks associated with aging infrastructure. The practice also introduced a new service related to Ecological Assets, a methodology that enables businesses with large land holdings to quantify the incremental benefits and value of those properties with respect to their ecological attributes. These “hidden values” can be used in credit systems such as wetland banks, carbon credits, offsets for resource damages, and valued ecological services.

Exponent has been engaged by a large electric and gas utility to develop a well defined, effective and efficient Quality Management System for several of its essential maintenance activities. This effort includes the development of: a policy document clearly stating management’s expectations with respect to the quality of the work performed and the controls necessary to insure in-process quality; detailed process maps outlining both the key maintenance activities and the organizational responsibility for each; associated work procedures; and the identification and analysis of key in-process metrics that allow management to determine what is working and what is not working. 5

The United States foods related business was highlighted by food contact notifications, generally recognized as safe submissions, nutritional assessments, and an array of contamination (microbiological, chemical, and physical) cases. The growth of the foods business led to the initiation of a foods offering group in the European Union.

Environmental and Earth Sciences Exponent’s environmental scientists and engineers provide proven, cost-effective, scientifically defensible and realistic assessments and solutions to complex environmental issues. We offer technical, regulatory and litigation support to industries that include mining and minerals, petrochemicals, forest products, shipbuilding, railroads, aerospace, and defense and trade associations. Our consultants also address hydrological issues related to new housing and office complex developments around the country.

Center for Epidemiology, Biostatistics & Computational Biology In 2008 our ecologists and resource economists expanded the services we provide companies and government agencies by assisting with strategic support on implementing strategies for identifying, accounting for, and sustaining ecological assets. We also provided engineering and environmental support related to financial transactions, including project finance, corporate finance, mergers and acquisitions, and structured finance. An area of particular opportunity for the firm has been in Latin America where we provided technical due-diligence on a refinery acquisition in Argentina and environmental and social due diligence services for companies in Columbia, Panama and the Dominican Republic.

Exponent health scientists apply epidemiologic methods to examine and solve complex health issues in a variety of settings. Through the principles of epidemiology, we analyze the interaction of host, agent, and environment to reach conclusions about the causes and occurrence of disease in human populations. Our scientists have successfully conducted numerous cancer cluster investigations, literature reviews, meta-analyses, and epidemiologic studies of various designs related to cancer concerns or allegations. These studies often involve collaboration with toxicology, exposure assessment, computer science, and medical personnel in other areas of the firm. Our epidemiologists’ expertise includes such diverse exposures as TCE, benzene, asbestos, radiation, chemotherapeutic agents, butadiene, ethylene oxide, dioxins, beryllium, chromium, radio frequency, electromagnetic fields, vinyl chloride, and others. Some of the cancers that we have studied are brain cancer, leukemia, non-Hodgkins lymphoma, breast cancer, lung cancer, mesothelioma, testicular cancer, and pancreatic cancer.

Health Sciences Center for Chemical Registration & Food Safety Our Center for Chemical Registration and Food Safety includes experienced staff of both technical and regulatory specialists who are experienced in dealing with foods, and with pesticide and nonpesticide products including conventional chemicals, biochemicals, microbials, biocides, products of biotechnology, and industrial chemicals. We provide practical, creative, scientific and regulatory support to assist global businesses at every stage of the product cycle, from research & development to retail and beyond.

Center for Exposure Assessment & Dose Reconstruction Exposure assessment is the science of estimating human exposure to chemical, physical, and biological agents, accounting for the frequency, magnitude, and duration of the exposure events. Exposure estimates can be compared to toxicity benchmarks or guidelines to assess potential risks to human health, and are used for many purposes, including in epidemiology, risk assessment, and regulatory compliance.

Highlights for 2008 include growth and expansion in current business sectors, as well as expansion into new areas. The United States pesticide service area continued to expand in 2008 with growth in product development and new United States product registration, due diligence, and data compensation areas, as well as the inert ingredients tolerance re-assessment and new approvals work.

Table of Contents In 2008, Exponent’s health professionals were retained to address emerging issues associated with benzene exposure from historical solvent uses, including publishing the results of an experiment on benzene exposures to solvent parts washers. Also, Exponent was heavily involved in current issues associated with lead exposure from items potentially used by children.

Human Factors Exponent’s Human Factors staff evaluates human performance and safety in product and system use. Our consultants study how the limitations and capabilities of people, including memory, perception, reaction time, judgment, physical size and dexterity affect the way they use a product, interact with an organization or environment, process information or participate in an activity.

Center for Public Health & Industrial Hygiene As part of our work, we reviewed labeling of over-the-counter (OTC) medications and consumer compliance with warnings on OTC labels. Some of the issues examined included label format, length, user comprehension, and the impact of including information about rare adverse events. We also examined physician compliance with information provided with prescription medications. In one project, work was done to examine factors influencing physician response to warnings against the co-prescription of specific drugs. Human factors analyses of the usability by consumers of different types of drug delivery systems were also an area of study.

This center is composed of scientists, engineers, physicians, and industrial hygienists, with specialized training in the anticipation, recognition, evaluation, risk assessment, and control of human health hazards. Our professional staff conducts workplace, community, environmental as well as occupational quantitative exposure measurements and human risk assessments. We also provide medical evaluations for clinical case findings. In 2008, this center worked on a number of national and international public health and industrial hygiene projects. Our projects ranged from site and plant surveys and sample collection, to major food and pharmaceutical recalls to technical support on large product liability lawsuits.

Industrial Structures Our Industrial Structures practice, based in Düsseldorf, Germany, specializes in design and assessment of industrial concrete structures subject to extreme conditions. Exponent’s Düsseldorf office has provided design reviews and assessments on more than 800 structures around the world, and our staff has participated in the creation of several engineering standards.

In 2008, we developed, implemented, and have ongoing oversight projects for workforce bio-monitoring programs for a major United States heavy equipment manufacturer and helped multiple companies evaluate the safety of their products, both in their production and customer utilization. We also assisted in the development of an emergency response plan for business and employees that also addresses community emergency response issues. Working for one of the largest property owners in the United States, we conducted 74 separate site inspections and risk assessments. In 2008, we also provided consultation to global companies addressing ongoing travel health issues in response to outbreaks of norovirus and outbreaks of Legionella.

Mechanical Engineering & Materials Science As the largest technical practice at Exponent, our mechanical engineers and materials scientists have both an academic and “realworld” understanding of their field, including failure analysis, materials characterization, reliability and hazard evaluation, design assessment and materials life prediction. We routinely work with manufacturers to assess risks to their products during their design and manufacturing phases of product development and recommend measures that could be taken to reduce those risks. For example, we frequently work with manufacturers to help them analyze allegations of defective design by the federal regulatory agencies such as the Consumer Product Safety Commission and the Food and Drug Administration.

Center for Toxicology & Mechanistic Biology Exponent’s expertise in toxicology and related disciplines provides critical insight for resolving important toxicity and risk issues related to a wide variety of chemicals. We evaluate mechanisms by which a substance or mixture may affect biological systems, determine potential health effects at realistic human and environmental exposure levels, and technically support strategies to mitigate risks. Exponent has developed new capabilities in neurotoxicology and developmental and reproductive toxicology to meet increasing legal and regulatory focus on effects of chemicals and pharmaceuticals on children’s health and endocrine disruption. There have also been significant additions to the center in pharmaceutical and pesticide scientific capabilities.

Table of Contents In addition to the above services, Exponent’s scientists and engineers are increasingly providing services in the area of patent litigation. As mechanical devices become increasingly complex, the technical staff members at Exponent are increasingly being asked to help interpret the language of the patent from a scientific and engineering perspective and provide valuable insight regarding the proper technical interpretation of the patent claims. For example, in 2008 the Mechanical Engineering and Materials Science practice was involved with a patent infringement case that was tried in the International Trade Commission (ITC) regarding certain components of refrigerators related to the ice making and delivery system. In this instance, Exponent was retained by the United States patent holder to review whether the ice making and delivery systems from a foreign manufacturer utilized the technologies described in the patent claim language. Exponent reviewed more than a dozen exemplar models from both the United States and the foreign manufacturers and performed a detailed part-by-part comparison of each of the units with the claim language. Exponent then provided several reports and trial testimony before the ITC judge regarding whether the products from the foreign manufacturer as well as those from the United States manufacturer are utilizing the technologies as described in the patent.

Technology Development Drawing on our multidisciplinary engineering, testing and failure analysis and prevention expertise, our Technology Development practice specializes in harnessing commercial technologies to develop effective military equipment and systems. In 2008, we continued to support the United States Army’s efforts in Afghanistan and Iraq. In the field, our engineers are assisting the Army’s Rapid Equipping Force to develop technical solutions to combat issues. We continue to supply the United States Army with Rapid Deployment Integrated Surveillance System to improve situational awareness for soldiers at joint security stations and combat outposts throughout Iraq. We have also been working with the United States Army to develop innovative application modules and personal area network technologies capable of supporting Future Warrior Technology Integration efforts. Thermal Sciences Exponent has investigated and analyzed thousands of fires and explosions ranging from high loss disasters at manufacturing facilities to small insurance claims. Information gained from these analyses has helped us assist clients in assessing preventative measures related to the design of their products. We also provide engineering analysis and pro-active risk support to a variety of industries.

Statistical & Data Sciences All living humans continually bear a certain degree of risk of injury or death. Exponent’s Statistical & Data Sciences (formerly Data & Risk Analysis) practice specializes in determining whether a particular activity or product poses an unreasonable risk. Risk estimation involves establishing a reference period and then collecting information about the number of injuries (or other adverse events) suffered and the amount of exposure during this period. The practice also provides statistical consulting services at all stages of the product life cycle to assist companies in addressing development, manufacturing, regulatory and safety issues.

For an operator of a natural gas storage field, Exponent used gas chemical composition and isotope data to investigate the migration of natural gas from an underground storage formation. Recently, pressure monitoring wells around the storage formation (storage field) indicated that a fault was leaking gas. Property owners adjacent to the field began producing gas that was claimed to be native gas and not the escaping storage gas. Exponent designed and supervised a field sampling and analysis program to collect samples from gas injection/withdrawal wells within the storage field and from gas observation wells surrounding the field. Through gas chemical composition and isotope analysis, Exponent was able to determine that the surrounding property owners are extracting storage gas, and assisted the storage field operator in filing a petition to expand the site boundaries to contain the escaped gas.

Since early 2008, Exponent statisticians have assisted a medical device manufacturer in developing its product for market. Exponent will manage and analyze the data generated from several clinical trials, some currently in progress, in accordance with Food and Drug Administration (FDA) guidelines. In addition, we have developed a customized clinical study design and analysis plan to meet the needs of the client, since existing industry standards for measuring device performance were not directly applicable. As part of the submission package to the FDA, we will report the results of the statistical data analysis and provide the client with technical and regulatory support as needed.

Vehicle Analysis Our Vehicle Analysis practice provides design analysis, vehicle crash testing, component testing and accident reconstruction services to clients developing new automotive products, facing unexpected performance issues, or seeking information on how an accident occurred.

Risk Factors Exponent operates in a rapidly changing environment that involves a number of uncertainties, some of which are beyond our control. These uncertainties include, but are not limited to, those mentioned elsewhere in this report and the following: Lack of sizable backlog may lead to less predictable, and perhaps lower, future revenues. Revenues are primarily derived from services provided in response to client requests or events that occur without notice, and engagements, generally billed as services are performed, are terminable or subject to postponement or delay at any time by clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods. Revenues and operating margins for any particular quarter are generally affected by staffing mix, resource requirements and timing and size of engagements. Failure to attract and retain key employees may adversely affect our business. Exponent’s business involves the delivery of professional services and is labor-intensive. Our success depends in large part upon our ability to attract, retain and motivate highly qualified technical and managerial personnel. Qualified personnel are in great demand and are likely to remain a limited resource for the foreseeable future. We cannot provide any assurance that we can continue to attract sufficient numbers of highly qualified technical and managerial personnel and to retain existing employees. The loss of key managerial employees or any significant number of employees could have a material adverse impact on our business, including our ability to secure and complete engagements.

Competition could reduce our pricing and adversely affect our business. The markets for our services are highly competitive. In addition, there are relatively low barriers to entry into our markets and we have faced, and expect to continue to face, additional competition from new entrants into our markets. Competitive pressure could reduce the market acceptance of our services and result in price reductions that could have a material adverse effect on our business, financial condition or results of operations. The loss of a large client could adversely affect our business. We currently derive and believe that we will continue to derive a significant portion of our revenues from clients, organizations and insurers related to the transportation industry and the government sector. For the fiscal year ended January 2, 2009, transportation industry related engagements accounted for approximately 14% of our revenues and government sector related engagements accounted for approximately 15% of our revenues. The loss of any large client, organization or insurer related to the transportation industry or the government sector could have a material adverse effect on our business, financial condition or results of operations. Our business can be adversely affected by downturns in the overall economy. The markets that we serve are cyclical and subject to general economic conditions. The direction and relative strength of the global economy has recently been increasingly uncertain. If the economy in the United States, where we primarily operate, were to experience a prolonged slowdown, demand for our services could be reduced considerably and our clients may consolidate or go out of business. We hold substantial investments that could present liquidity risks. Our cash equivalent and investment portfolio as of January 2, 2009 consisted primarily of obligations of state and local government agencies. We follow an established investment policy to monitor, manage and limit our exposure to interest rate and credit risk. The policy sets forth credit quality standards and limits our exposure to any one issuer, as well as our maximum exposure to various asset classes. 13

Table of Contents As a result of current adverse financial market conditions, investments in some financial instruments may pose risks arising from liquidity and credit concerns. As of January 2, 2009, we had no impairment charge associated with our investment portfolio relating to such adverse financial market conditions. Although we believe our current investment portfolio has a low risk of impairment, we cannot predict future market conditions or market liquidity and can provide no assurance that our investment portfolio will remain unimpaired.

engagements commenced and completed during a quarter, the timing of engagements, the number of working days in a quarter, employee hiring and utilization rates, and integration of companies acquired. Because a high percentage of our expenses, particularly personnel and facilities related expenses, are relatively fixed in advance of any particular quarter, a variation in the timing of the initiation or the completion of our client assignments can cause significant variations in operating results from quarter to quarter. Item 1B. Unresolved Staff Comments

Our business is dependent on our professional reputation. The professional reputation of Exponent and its consultants is critical to our ability to successfully compete for new client engagements and attract or retain professionals. Any factors that damage our professional reputation could have a material adverse effect on our business. Our business can be adversely impacted by deregulation or reduced regulatory enforcement. Public concern over health, safety and preservation of the environment has resulted in the enactment of a broad range of environmental and/or other laws and regulations by local, state and federal lawmakers and agencies. These laws and the implementing of new regulations affect nearly every industry, as well as the agencies of federal, state and local governments charged with their enforcement. To the extent changes in such laws, regulations and enforcement or other factors significantly reduce the exposures of manufacturers, owners, service providers and others to liability, the demand for our services may be significantly reduced. Tort reform can reduce demand for our services. Several of our practices have a significant concentration in litigation support consulting services. To the extent tort reform reduces the exposure of manufacturers, owners, service providers and others to liability, the demand for our litigation support consulting services may be significantly reduced. Our quarterly results may vary.

Properties Our Silicon Valley office facilities consist of a 153,738 square foot building, with office and laboratory space located on a 6.3-acre tract of land we own in Menlo Park, California and an adjacent 27,000 square feet of leased warehouse storage space. Our Test and Engineering Center (TEC) occupies 147 acres in Phoenix, Arizona. We lease this land from the state of Arizona under a 30-year lease agreement that expires in January 2028 and have options to renew for two fifteen-year periods. We constructed an indoor test facility as well as an engineering and test preparation building at the TEC. In addition, we lease office, warehouse and laboratory space in 21 other locations in 13 states and the District of Columbia, as well as in Germany, China, Switzerland and the United Kingdom. Leases for these offices, warehouse and laboratory facilities have terms generally ranging between one and ten years. Aggregate lease expense in fiscal 2008 for all leased properties was $5,110,000. Item 3. Legal Proceedings Exponent is not engaged in any material legal proceedings. Item 4. Submission of Matters to a Vote of Security Holders No matters were submitted to a vote of security holders during the fourth quarter of fiscal 2008.

Variations in our revenues and operating results occur from time to time, as a result of a number of factors, such as the significance of client 14

Table of Contents Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Overview Exponent, Inc. is a science and engineering consulting firm that provides solutions to complex problems. Our multidisciplinary team of scientists, physicians, engineers, business and regulatory consultants brings together more than 90 different technical disciplines to solve complicated issues facing industry and government today. Our services include analysis of products, people, property, processes and finances related to litigation, product recall, regulatory compliance, research, development and design. CRITICAL ACCOUNTING ESTIMATES In preparing our consolidated financial statements, we make assumptions, judgments and estimates that can have a significant impact on our revenue, operating income and net income, as well as on the value of certain assets and liabilities on our consolidated balance sheet. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a regular basis we evaluate our assumptions, judgments and estimates and make changes accordingly. We believe that the assumptions, judgments and estimates involved in the accounting for revenue recognition and estimating the allowance for doubtful accounts have the greatest potential impact on our consolidated financial statements, so we consider these to be our critical accounting policies. We discuss below the assumptions, judgments and estimates associated with these policies. Historically, our assumptions, judgments and estimates relative to our critical accounting policies have not differed materially from actual results. For further information on our critical accounting policies, see Note 1 of our Notes to Consolidated Financial Statements. Revenue recognition. We derive our revenues primarily from professional fees earned on consulting engagements, product sales in our technology development practice, fees earned for the use of our equipment and facilities, as well as reimbursements for outside direct expenses associated with the services that are billed to our clients.

Substantially all of our engagements are performed under time and material or fixed-price billing arrangements. On time and material and fixed-price projects, revenue is generally recognized as the services are performed. For substantially all of our fixed-price engagements we recognize revenue based on the relationship of incurred labor hours at standard rates to our estimate of the total labor hours at standard rates we expect to incur over the term of the contract. Our estimate of total labor hours we expect to incur over the term of the contract is based on the nature of the project and our past experience on similar projects. We believe this methodology achieves a reliable measure of the revenue from the consulting services we provide to our customers under fixed-price contracts. Significant management judgments and estimates must be made and used in connection with the revenues recognized in any accounting period. These judgments and estimates include an assessment of collectibility and, for fixed-price engagements, an estimate as to the total effort required to complete the project. If we made different judgments or utilized different estimates, the amount and timing of our revenue for any period could be materially different. All contracts are subject to review by management, which requires a positive assessment of the collectibility of contract amounts. If, during the course of the contract, we determine that collection of revenue is not reasonably assured, we do not recognize the revenue until its collection becomes reasonably assured, which in those situations would generally be upon receipt of cash. We assess collectibility based on a number of factors, including past transaction history with the client, as well as the credit-worthiness of the client. Losses on fixed-price contracts are recognized during the period in which the loss first becomes evident. Contract losses are determined to be the amount by which the estimated total costs of the contract exceeds the total fixed price of the contract. Estimating the allowance for doubtful accounts. We must make estimates of our ability to collect accounts receivable and our unbilled work-in-process. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations to us, we record a specific allowance to reduce the net recognized receivable to the amount we reasonably believe will be collected. For all other customers we recognize allowances for doubtful accounts based upon historical bad debts, customer concentration, customer credit-worthiness, current economic conditions, aging of amounts due and changes in customer payment terms. As of January 2, 2009, our accounts receivable balance was $62.2 million, net of an allowance for doubtful accounts of $2.4 million. 18

Our revenue growth was driven primarily by an increase in billable hours, higher billing rates and an increase in product sales in our technology development practice. Total billable hours increased 7.6% to 888,000 during fiscal 2008 as compared to 825,000 during fiscal 2007. The increase in billable hours was due to an increase in technical full-time equivalent employees and fiscal 2008 having one additional week of activity than fiscal 2007. Total billable hours during the 53rd week of fiscal 2008 were 7,791, which contributed approximately $1.8 million to the increase in revenue. Utilization decreased to 67% for fiscal 2008 as compared to 68% for fiscal 2007. Technical full-time equivalent employees increased by 7.3% to 624 during fiscal 2008 as compared to 581 during fiscal 2007. This increase in technical full time equivalent employees was due to our continued recruiting and retention efforts. Product sales in our 19

Table of Contents technology development practice increased 18% to $14.1 million for fiscal 2008 as compared to $11.9 million for fiscal 2007. This increase in product sales was primarily due to an increase in sales of surveillance systems to the United States Army.

Utilization for this segment decreased to 65% for fiscal 2008 as compared to 67% for fiscal 2007. Technical full-time equivalent employees for this segment increased by 8.1% to 161 during fiscal 2008 as compared to 149 during fiscal 2007.

The increase in billable hours, product sales and the management of our operating expenses, allowed us to leverage this revenue growth to improve operating income by 22.6% and net income by 13.9%.

Revenues are primarily derived from services provided in response to client requests or events that occur without notice and engagements are generally terminable or subject to postponement or delay at any time by our clients. As a result, backlog at any particular time is small in relation to our quarterly or annual revenues and is not a reliable indicator of revenues for any future periods.

The net increase in compensation and related expenses during fiscal 2008 was due to an increase in wages, fringe benefits and bonus expense partially offset by the change in value of assets associated with our deferred compensation plan. Wages increased by $11.0 million and fringe benefits increased by $2.5 million due to an increase in technical full-time equivalent employees, the impact of our annual salary increase and fiscal 2008 having one additional week of activity than fiscal 2007. The additional week of activity during fiscal 2008 contributed approximately $1.3 million to the increase in wages. Bonus expense increased by $1.7 million due to a corresponding increase in profitability. During fiscal 2008, we recorded a decrease to compensation expense of $2.1 million and a corresponding decrease to other income of $2.1 million associated with a decline in the value of assets associated with our deferred compensation plan. During fiscal 2007 we recorded an increase in compensation expense of $356,000 and a corresponding increase to other income of $356,000 associated with a gain in the value of plan assets during fiscal 2007. We expect compensation and related expenses, excluding the change in value of assets associated with our deferred compensation plan, to increase due to the anticipated hiring of additional staff and the impact of future annual salary increases.

The net increase in other operating expenses was primarily due to an increase of $732,000 in occupancy expense and an increase of $285,000 in depreciation and amortization. The increase in occupancy expense and depreciation and amortization were due to expansion in certain offices to support our increase in technical-full time equivalent employees.

Other income and expense, net, consists primarily of investment income earned on available cash, cash equivalents and short-term investments, rental income from leasing excess space in our Silicon Valley facility, and changes in the value of assets associated with our deferred compensation plan. The decrease in other income and expense, net, during fiscal 2008 was primarily due to a decrease in the fair value of deferred compensation assets of $2.1 million with a corresponding decrease of $2.1 million to compensation and related expenses during fiscal 2008 as compared to an increase in the fair value of deferred compensation assets of $356,000 with a corresponding increase of $356,000 to compensation and related expenses during fiscal 2007. The decrease in valuation of deferred compensation investments was partially offset by an increase in rental income of $404,000 and an increase in gain on foreign exchange of $347,000. Rental income increased due to the addition of a new tenant in our Silicon Valley facility in mid 2007. Income Taxes (In thou san ds e xce pt pe rce n tage s)

The increase in personnel expense was primarily due to the costs associated with professional development and recruiting. The increase in travel and meals was primarily due to an increase in technical full-time equivalent employees as well as an increase in fuel costs. The increase in bad debt expense was due to an increase in write-offs and an increase in our allowance for doubtful accounts.

The increase in revenues for our engineering and other scientific segment during fiscal 2007 was the result of an increase in billable hours, higher billing rates and an increase in product sales in our technology development practice. During fiscal 2007, billable hours for this segment increased by 6.0% to 617,000 as compared to 582,000 during fiscal 2006. The increase in billable hours was supported by an increase in utilization and technical full-time equivalent employees. Utilization for this segment increased to 69% for fiscal 2007 as compared to 67% for fiscal 2006. Technical full-time equivalents for this segment increased by 3.1% to 432 during fiscal 2007, as compared to 419 during fiscal 2006.

In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 141 (revised 2007) (“SFAS 141R”), “Business Combinations” and SFAS No. 160 (“SFAS 160”), “Noncontrolling Interests in Consolidated Financial Statements, an Amendment of Accounting Research Bulletin, No. 51.” SFAS 141R will change how business acquisitions are accounted for and will impact financial statements both on the acquisition date and in subsequent periods. SFAS 160 will change the accounting and reporting for minority interests, which will be recharacterized as noncontrolling interests and classified as a component of equity. SFAS 141R and SFAS 160 are effective for fiscal years beginning after November 15, 2008. We intend to adopt SFAS 141R and SFAS 160 in fiscal 2009 and do not expect it to have a material impact on our consolidated financial position, results of operations or cash flows. In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (“SFAS 157”), “Fair Value Measurements,” which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. SFAS 157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements and is effective for fiscal years beginning after November 15, 2007. In February 2008, the FASB issued FASB Staff Position 157-2 which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), until fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. These nonfinancial items include assets and liabilities such as reporting units measured at fair value in a goodwill impairment test and nonfinancial assets acquired and liabilities assumed in a business combination. Effective December 29, 2007, we adopted SFAS 157 for financial assets and liabilities recognized at fair value on a recurring basis. The partial adoption of SFAS 157 for financial assets and liabilities did not have a material impact on our consolidated financial position, results of operations or cash flows. We intend to adopt FASB Staff Position 157-2 in fiscal 2009 and do not expect it to have a material impact on our consolidated financial position, results of operations or cash flows.

We financed our business in fiscal 2008 principally through available cash and cash flows from operating activities. We invest our excess cash in cash equivalents and short-term investments. At the end of fiscal 2008, we had $57.4 million in cash, cash equivalents and short-term investments compared to $63.7 million at the end of the prior year. The increase in cash provided by operating activities during fiscal 2008 as compared to fiscal 2007 was due to an increase in net income and a smaller increase in accounts receivable partially offset by a decrease in deferred revenues. During fiscal 2008, accounts receivable increased by $5.1 million as compared to an increase of $14.1 million during fiscal 2007. The smaller increase in accounts receivable was due to slower revenue growth. During fiscal 2008, revenue increased by 11.5% as compared to an increase of 21.8% during fiscal 2007. Days sales outstanding increased to 97 days at the end of fiscal 2008 as compared to 88 days at the end of fiscal 2007. During fiscal 2008, deferred revenues decreased by $287,000 as compared to an increase of $2.4 million during fiscal 2007. The large increase during fiscal 2007 was due to an increase in pre-billed projects. The increase in cash provided by operating activities during fiscal 2007 as compared to fiscal 2006 was due to an increase in net income, a larger increase in accrued payroll and employee benefits, a larger increase in accounts payable and accrued liabilities, and an increase in stock-based compensation partially offset by a larger increase in accounts receivable. The larger increase in accrued payroll and employee benefits was primarily due to an increase in accrued bonuses driven by a corresponding increase in profitability. The larger increase in accounts payable and accrued liabilities was due to the timing of payments to our vendors. The increase in stockbased compensation was due to additional restricted stock unit grants during fiscal 2007 and an increase in the accrued bonus that we expect to settle with fully vested restricted stock units. The larger increase in accounts receivable was due to an increase in revenues. Days sales outstanding decreased to 88 days at the end of fiscal 2007 as compared to 94 days at the end of fiscal 2006.

The increase in net cash used in financing activities during fiscal 2008, as compared to fiscal 2007, was due to an increase in repurchases of our common stock under our stock repurchase programs. The decrease in net cash used in financing activities during fiscal 2007, as compared to fiscal 2006, was due to a decrease in repurchases of our common stock under our stock repurchase programs partially offset by an increase in proceeds from the issuance of common stock. Proceeds from the issuance of common stock are primarily related to the exercise of employee stock options and the purchase of common stock under our employee stock purchase plan. We expect to continue our investing activities, including purchases of short-term investments and capital expenditures. Furthermore, cash reserves may be used to repurchase common stock under our stock repurchase programs or strategically acquire professional services firms that are complementary to our business. The following schedule summarizes our principal contractual commitments as of January 2, 2009 (in thousands):

Table of Contents We maintain a nonqualified deferred compensation plan for the benefit of a select group of highly compensated employees. Vested amounts due under the plan of $4.4 million were recorded as a longterm liability on our consolidated balance sheet at January 2, 2009. Company assets that are earmarked to pay benefits under the plan are held in a rabbi trust and are subject to the claims of our creditors. As of January 2, 2009, invested amounts under the plan of $4.4 million were recorded as a long-term asset on our consolidated balance sheet. As permitted under Delaware law, we have agreements whereby we indemnify our officers and directors for certain events or occurrences while the officer or director is, or was serving, at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the officer’s or director’s lifetime. The maximum potential amount of future payments we could be required to make under these indemnification agreements is unlimited; however, we have director and officer insurance coverage that reduces our exposure and enables us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal. Off-Balance Sheet Arrangements As part of our ongoing business, we do not engage in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities.

We are exposed to liquidity and credit risk associated with a student loan secured auction rate security. Included within our investment portfolio and classified as a long-term asset on our balance sheet at January 2, 2009 is one AA rated student loan secured auction rate security with a par value of $1.0 million. During the second quarter of 2008, the auction for this security failed. The issuer has expressed its intent to restructure this security, and the next scheduled auction is in May of 2009. We will not have access to these funds until the security is restructured or a future auction is successful. If the issuer is unable to restructure this security or successfully close future auctions and its credit ratings deteriorate, we may be required to adjust the carrying value of this investment through an impairment charge. During the fourth quarter of 2008, we recorded an unrealized loss on our auction rate security of $125,000, which is reflected in other comprehensive income in our consolidated balance sheet. Based on our ability to access our cash and shortterm investments, our expected operating cash flows, and our other sources of cash we do not expect any lack of liquidity related to this investment to negatively impact our ability to operate our business as usual. We are exposed to some foreign currency exchange rate risk associated with our foreign operations. Given the limited nature of these operations, we believe that any exposure would be minimal. Item 8. Financial Statements and Supplementary Data See Item 15 of this Form 10-K for required financial statements and supplementary data.

Item 7A. Quantitative and Qualitative Disclosure About Market Risk

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

Exponent is exposed to interest rate risk associated with our balances of cash, cash equivalents and investments. We manage our interest rate risk by maintaining an investment portfolio primarily consisting of debt instruments with high credit quality and relatively short average effective maturities (auction rate maturity set at date of next auction) in accordance with the Company’s investment policy. The maximum effective maturity of any issue in our portfolio of cash equivalents and investments is 3 years and the maximum average effective maturity of the portfolio cannot exceed 12 months.

None.

Our exposure to market rate risk for changes in interest rates relates primarily to our investments. We do not use derivative financial instruments in our investment portfolio. The average effective maturity of our investment portfolio and cash equivalents at January 2, 2009 was 0.51 years. Notwithstanding our efforts to manage interest rate risk, there can be no assurances that we will be adequately protected against the risks associated with interest rate fluctuations.

Table of Contents Report of Independent Registered Public Accounting Firm The Board of Directors and Stockholders Exponent, Inc.: We have audited the accompanying consolidated balance sheets of Exponent, Inc. and subsidiaries (the Company) as of January 2, 2009 and December 28, 2007, and the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended January 2, 2009. In connection with our audits of the consolidated financial statements, we have also audited the accompanying financial statement schedule II. We also have audited the Company’s internal control over financial reporting as of January 2, 2009, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting, appearing under Item 9A(b). Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule II, and an opinion on the Company’s internal control over financial reporting based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Table of Contents Exponent, Inc. and Subsidiaries Notes to Consolidated Financial Statements Note 1: Summary of Significant Accounting Policies

The Company reports service revenues net of subcontractor fees. The Company has determined that it is not the primary obligor with respect to these subcontractors because: • its clients are directly involved in the subcontractor selection process; • the subcontractor is responsible for fulfilling the scope of work; and • the Company passes through the costs of subcontractor agreements with only a minimal fixed percentage mark-up to compensate it for processing the transactions.

Basis of Presentation Exponent, Inc. together with its subsidiaries (collectively referred to as the “Company”) is a science and engineering consulting firm that provides solutions to complex problems. The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Company operates on a 52-53 week fiscal year with each year ending on the Friday closest to December 31st. Fiscal period 2008 included 53 weeks of activity and ended on January 2, 2009. Fiscal periods 2007 and 2006 included 52 weeks of activity and ended on December 28, 2007 and December 29, 2006, respectively. Stock Split On May 24, 2006, the Company’s stockholders approved an amendment to the Company’s certificate of incorporation to (i) increase the number of authorized shares of common stock to 100,000,000, (ii) increase the number of authorized shares of preferred stock to 5,000,000, and (iii) effect a two-for-one stock split. As a result of the stock split, each shareholder of record at the close of business on May 24, 2006, received one additional share of common stock for each share held. For periods prior to the stock split, all share and per share data in the Company’s consolidated financial statements and related notes have been retroactively adjusted to reflect the stock split.

Reimbursements, including those related to travel and other out-ofpocket expenses, and other similar third party costs such as the cost of materials, are included in revenues, and an equivalent amount of reimbursable expenses are included in operating expenses. Any mark-up on reimbursable expenses is included in revenues. Substantially all of the Company’s engagements are performed under time and material or fixed-price billing arrangements. On time and material and fixed-price projects, revenue is generally recognized as the services are performed. For substantially all of the Company’s fixed-price engagements, it recognizes revenue based on the relationship of incurred labor hours at standard rates to its estimate of the total labor hours at standard rates it expects to incur over the term of the contract. The Company believes this methodology achieves a reliable measure of the revenue from the consulting services it provides to its customers under fixed-price contracts given the nature of the consulting services the Company provides and the following additional considerations: • the Company considers labor hours at standard rates and expenses to be incurred when pricing its contracts; • the Company generally does not incur set up costs on its contracts; • the Company does not believe that there are reliable milestones to measure progress toward completion; • if the contract is terminated early, the customer is required to pay the Company for time at standard rates plus materials incurred to date;

The Company committed to stockholders in a letter dated May 23, 2006 to limit its use of the increased authorized capital stock to 40 million common shares, and 2 million preferred shares, unless the approval of the Company’s stockholders is obtained subsequently, such as through a further amendment to the Company’s authorized capital stock. Revenue Recognition The Company derives its revenues primarily from professional fees earned on consulting engagements, product sales in its technology development practice, fees earned for the use of its equipment and facilities, as well as reimbursements for outside direct expenses associated with the services that are billed to its clients.

Table of Contents • the Company does not recognize revenue for award fees or bonuses until specific contractual criteria are met; • the Company does not include revenue for unpriced change orders until the customer agrees with the changes; • historically the Company has not had significant accounts receivable write-offs or cost overruns; and • its contracts are typically progress billed on a monthly basis. Product revenue is recognized, when both title and risk of loss transfer to the customer and customer acceptance has occurred, provided that no significant obligations remain. Revenue from multiple-element arrangements is allocated based on the relative fair value of each element, which is generally based on the relative sales price for each element when sold separately. If the fair value of one or more delivered elements cannot be determined revenue is allocated based on the residual method. Gross revenues and reimbursements for the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006, respectively, were:

Significant management judgments and estimates must be made in connection with the revenues recognized in any accounting period. These judgments and estimates include an assessment of collectibility and, for fixed-price engagements, an estimate as to the total effort required to complete the project. If the Company made different judgments or utilized different estimates, the amount and timing of its revenue for any period could be materially different.

All contracts are subject to review by management, which requires a positive assessment of the collectibility of contract amounts. If, during the course of the contract, the Company determines that collection of revenue is not reasonably assured, it does not recognize the revenue until its collection becomes reasonably assured, which in those situations would generally be upon receipt of cash. The Company assesses collectibility based on a number of factors, including past transaction history with the client, as well as the credit-worthiness of the client. Losses on fixed-price contracts are recognized during the period in which the loss first becomes evident. Contract losses are determined to be the amount by which the estimated total costs of the contract exceeds the total fixed price of the contract. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates. Foreign Currency Translation The Company translates the assets and liabilities of foreign subsidiaries, whose functional currency is the local currency, at exchange rates in effect at the balance sheet date. Revenues and expenses are translated at the average rates of exchange prevailing during the year. The adjustment resulting from translating the financial statements of such foreign subsidiaries is included in accumulated other comprehensive income, which is reflected as a separate component of stockholders’ equity. Cash Equivalents Cash equivalents consist of highly liquid investments such as money market mutual funds, commercial paper and debt securities with original maturities of three months or less. Investments Investments consist of debt securities classified as available-forsale and are carried at their fair value as of the balance sheet date. Short-term investments generally mature between three months and three years from the purchase date. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent investments readily available for current operations. At January 2, 2009, the Company held one AA rated student loan secured auction rate security with a fair value of $875,000 classified as a non-current asset on its balance sheet. 36

Table of Contents The amortized cost of securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization is included in interest income. Realized gains or losses are determined on the specific identification method and are reflected in other income. Net unrealized gains and losses are recorded directly in accumulated other comprehensive income except for unrealized losses that are deemed to be other-than-temporary, which are reflected in net income. Investments are reviewed on a regular basis to evaluate whether or not any security has experienced an other-than temporary decline in fair value. When assessing investments for other-than-temporary declines in fair value, the Company considers the significance of the decline in value as a percentage of the original cost, how long the market value of the investment has been less than its original cost, and any news that has been released specific to the investee. Allowances for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of customers to meet their financial obligations. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations a specific allowance is recorded to reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers the Company recognizes allowances for doubtful accounts based upon historical bad debts, customer concentration, customer credit-worthiness, current economic conditions, aging of amounts due and changes in customer payment terms. Property, Equipment and Leasehold Improvements Property, equipment and leasehold improvements are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are recognized using the straight-line method. Buildings are depreciated over their estimated useful lives ranging from thirty to forty years. Equipment is depreciated over its estimated useful life, which generally ranges from two to seven years. Leasehold improvements are amortized over the shorter of their estimated useful lives, generally seven years, or the term of the related lease.

Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future cash flows to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company has not recognized impairment losses on any long-lived assets in fiscal 2008, 2007 or 2006. Goodwill The Company assesses the impairment of goodwill annually and whenever events or changes in circumstances indicate that the carrying amount may be impaired. The Company’s annual goodwill impairment review is completed at the end of the 47th week of each fiscal year. Factors that the Company considers when evaluating for possible impairment include the following: • significant under-performance relative to expected historical or projected future operating results; • significant changes in the manner of use of the acquired assets or the strategy for overall business; and • significant negative economic trends. When evaluating the Company’s goodwill for impairment, based upon the existence of one or more of the above factors, the Company determines the existence of an impairment by assessing the fair value of the applicable reporting unit, including goodwill, using expected future cash flows to be generated by the reporting unit. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reporting unit’s goodwill over the implied fair value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit in a manner similar to a purchase price allocation, in accordance with FASB Statement No. 141, Business Combinations. The residual fair value after this allocation is the implied value of the reporting unit goodwill. The Company did not recognize any goodwill impairment losses in fiscal 2008, 2007 or 2006.

Table of Contents Deferred Revenues Deferred revenues represent amounts billed to clients in advance of services provided, primarily on fixed-price projects. The Company had $6,171,000 and $6,458,000 in deferred revenues as of January 2, 2009 and December 28, 2007, respectively.

The following schedule reconciles the denominators of the Company’s calculation for basic and diluted net income per share:

(In thou san ds)

Shares used in basic per share computation Effect of dilutive common stock options outstanding Effect of non-vested restricted stock units outstanding Shares used in diluted per share computation

Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis and the financial reporting basis of assets and liabilities. Deferred tax assets and liabilities are measured using the enacted tax rates and laws in effect when the differences are expected to reverse. The effect on deferred tax assets and liabilities from changes in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is recorded for deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. United States income taxes are provided on the earnings of foreign subsidiaries unless the subsidiaries earnings are considered permanently reinvested outside the United States. Fair Value of Financial Instruments Financial instruments consist of cash and cash equivalents, shortterm investments, accounts receivable, other assets and accounts payable. The carrying amount of the Company’s cash and cash equivalents, short-term investments, accounts receivable, other assets and accounts payable approximates their fair values. Stock-Based Compensation Stock-based compensation is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite service period. The Company estimates the number of awards that are expected to vest and revises the estimate as actual forfeitures differ from that estimate. Estimated forfeiture rates are based on the Company’s historical experience. Net Income Per Share Basic per share amounts are computed using the weighted-average number of common shares outstanding during the period. Dilutive per share amounts are computed using the weighted-average number of common shares outstanding and potentially dilutive securities, using the treasury stock method if their effect would be dilutive.

Common stock options to purchase 53,854 shares, with exercise prices greater than the annual average fair market value of the Company’s common stock, were excluded from the diluted per share calculation for the fiscal year ended January 2, 2009. There were no options excluded from the diluted per share calculation for the fiscal years ended December 28, 2007 and December 29, 2006. Recently Adopted Accounting Pronouncements In September 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 157 (“SFAS 157”), “Fair Value Measurements,” which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. SFAS 157 does not require any new fair value measurements but rather eliminates inconsistencies in guidance found in various prior accounting pronouncements and is effective for fiscal years beginning after November 15, 2007. In February 2008, the FASB issued FASB Staff Position 157-2 which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis (at least annually), until fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. These nonfinancial items include assets and liabilities such as reporting units measured at fair value in a goodwill impairment test and nonfinancial assets acquired and liabilities assumed in a business combination. Effective December 29, 2007, the Company adopted SFAS 157 for financial assets and liabilities recognized at fair value on a recurring basis. The partial adoption of SFAS 157 for financial assets and liabilities did not have a material impact on the Company’s consolidated financial position, results of operations or cash flows. See Note 3 for information and related disclosures regarding fair value measurements.

Market values were determined for each individual security in the investment portfolio. The declines in value of these investments are primarily related to changes in interest rates and are considered to be temporary in nature. All cash equivalents and short-term investments had effective maturities of three years or less, with an average effective maturity of 0.51 years as of January 2, 2009. Note 3: Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis, including available-for-sale fixed income securities, trading fixed income and equity securities held in its deferred compensation plan and the liability associated with its deferred compensation plan. The fair value of these certain financial assets and liabilities was determined using the following inputs at January 2, 2009 (in thousands):

Table of Contents Included within the Company’s investment portfolio and classified as a long-term asset on its balance sheet is one AA rated student loan secured auction rate security purchased for $1 million. During the second quarter of 2008, the auction for this security failed. Due to the failed auction, the Company concluded that this auction rate security represents a Level 3 valuation within the SFAS No. 157 hierarchy. The auction rate security was valued based on a discounted cash flow analysis and the Company recorded an unrealized loss on the auction rate security of $125,000, which is reflected in other comprehensive income in the consolidated balance sheet. The Company intends to hold this security until a future auction is successful or the security is restructured. Note 4: Property, Equipment and Leasehold Improvements Fiscal Ye ars 2008 2007

Management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize the net deferred tax assets. The Company is entitled to a deduction for federal and state tax purposes with respect to employees’ stock award activity. The net deduction in taxes otherwise payable arising from that deduction has been credited to additional paid-in capital. For the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006, the net deduction in tax payable arising from employees’ stock option activity was $5,551,000, $3,989,000 and $869,000 respectively. The Company and its subsidiaries file income tax returns in the United States federal jurisdiction, California and various other state and foreign jurisdictions. The Company is no longer subject to United States federal income tax examination for years prior to 2005. The Company is no longer subject to California franchise tax examinations for years prior to 2004. With few exceptions, the Company is no longer subject to state and local or non-United States income tax examination by tax authorities for years prior to 2004.

The Company adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes”, on December 30, 2006. At December 30, 2006, the Company had unrecognized tax benefits of $258,000, which primarily related to uncertainty regarding the sustainability of certain deductions taken on the Company’s federal and state income tax returns. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Balance at December 30, 2006 Additions based on tax positions related to the current year Additions for tax positions of prior years Reductions due to lapse of statute of limitations Settlements Balance at December 28, 2007 Additions based on tax positions related to the current year Additions for tax positions of prior years Reductions due to lapse of statute of limitations Settlements Balance at January 2, 2009

$ 258,000 54,000 3,000 (45,000) (5,000) 265,000 83,000 5,000 (38,000) — $ 315,000

Unrecognized tax benefits are included in other liabilities in the accompanying balance sheet. To the extent these unrecognized tax benefits are ultimately recognized, they will impact the effective tax rate in a future period. There are no uncertain tax positions whose resolution in the next 12 months is expected to materially affect operating results. The Company’s policy is to recognize interest and penalties related to unrecognized tax benefits as income tax expense. Accrued interest and penalties are insignificant at January 2, 2009. Deferred income taxes have not been provided on the undistributed earnings of foreign subsidiaries. The amount of such earnings at January 2, 2009 was $1,232,000. These earnings have been permanently reinvested and the Company does not plan to initiate any action that would precipitate the payment of income taxes thereon. It is not practicable to estimate the amount of additional tax that might be payable on the undistributed foreign earnings.

None of the preferred shares were issued and outstanding at January 2, 2009 and December 28, 2007.

The 2008 Equity Incentive Plan allows for the award of stock options, stock awards (including stock units, stock grants and stock appreciation rights or other similar equity awards) and cash awards to officers, employees, consultants and non-employee members of the Board of Directors. The total number of shares available for issuance under the 2008 Equity Incentive Plan is 1,200,000 shares of common stock, subject to adjustment resulting from a stock split or the payment of a stock dividend or any other increase or decrease in the number of issued shares of the Company’s stock effected without receipt of consideration by the Company. For the fiscal year ended January 2, 2009, 8,020 restricted stock unit awards were granted under the plan, leaving 1,191,980 shares available for grant.

Accumulated Other Comprehensive Income Accumulated other comprehensive income consists of cumulative foreign currency translation adjustments and unrealized gains or losses on investments. Treasury Stock Net losses related to the re-issuance of treasury stock of $9,051,000, $8,549,000 and $1,290,000 were recorded as a reduction to retained earnings during fiscal 2008, 2007 and 2006, respectively. Repurchase of Common Stock The Company repurchased 1,409,000 shares of its common stock for $41.3 million during the fiscal year ended January 2, 2009.

As of January 2, 2009, the Company had remaining authorization under its stock repurchase plan of $9.9 million to repurchase shares of common stock.

The ESPP allows for officers and employees to purchase common stock through payroll deductions of up to 15% of a participant’s eligible compensation. Shares of common stock are purchased under the ESPP at 95% of the fair market value of the Company’s common stock on each purchase date. Subject to adjustment resulting from a stock split or the payment of a stock dividend or any other increase or decrease in the number of issued shares of the Company’s stock effected without receipt of consideration by the Company, the total number of shares available for issuance under the ESPP is 200,000 shares of common stock. For the period ending January 2, 2009, 17,518 shares were purchased under the plan, leaving a balance of 182,482 shares available for purchase. Weighted average purchase prices for shares sold under all ESPP plans in fiscal 2008, 2007 and 2006 were $29.97, $22.33 and $16.06, respectively.

Note 9: Stock-Based Compensation On May 29, 2008, the Company’s stockholders approved the 2008 Equity Incentive Plan and the 2008 Employee Stock Purchase Plan (“ESPP”). The 2008 Equity Incentive Plan and ESPP were previously adopted by the Company’s Board of Directors on April 8, 2008, subject to stockholder approval.

Restricted Stock Units The Company grants restricted stock units to employees and outside directors. These restricted stock unit grants are designed to attract and retain employees, and to better align employee interests with those of the Company’s stockholders. For a select group of employees, up to 40% of their annual bonus is settled with fully vested restricted stock unit awards. Under these fully vested restricted stock unit awards, the holder of each award has the right to receive one share of the Company’s common stock for each fully vested restricted stock unit four years from the date of grant. Each individual who received a fully vested restricted stock unit award is also granted a matching number of unvested restricted stock unit awards. These unvested restricted stock unit awards cliff vest four years from the date of grant, at which time the holder of each award will have the right to receive one share of the Company’s common stock for each restricted stock unit award provided the holder of each award has met certain employment conditions. In the case of retirement at 59 1/2 years or older, all unvested restricted stock unit awards will continue to vest provided the holder of each award does all consulting work through the company and does not become an employee for a past or present client, beneficial party or competitor of the company. The value of these restricted stock unit awards is determined based on the market price of the Company’s common stock on the date of grant. The value of fully vested restricted stock unit awards issued is recorded as a reduction to accrued bonuses. The portion of bonus expense that the Company expects to settle with fully vested restricted stock unit awards is recorded as stock-based compensation during the period the bonus is earned.

The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $3,032,000, $1,887,000 and $1,223,000 during the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006, respectively. Stock Options The Company currently grants stock options under the 2008 Equity Incentive Plan. Options are granted for terms of ten years and generally vest ratably over a four-year period from the grant date. The Company grants options at exercise prices equal to the fair value of the Company’s common stock on the date of grant. During the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006, respectively, the Company recorded stock-based compensation expense of $231,000, $447,000 and $862,000 associated with stock options granted prior to, but not yet vested as of December 30, 2005. During the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006, respectively, the Company recorded stock-based compensation expense of $499,000, $296,000 and $112,000 associated with stock options granted after December 30, 2005. 46

Table of Contents Stock-Based Compensation The Company uses the Black-Scholes option-pricing model to determine the fair value of options granted. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company used historical exercise and post-vesting forfeiture and expiration data to estimate the expected term of options granted. The historical volatility of the Company’s common stock over a period of time equal to the expected term of the options granted was used to estimate expected volatility.

The risk-free interest rate used in the option-pricing model was based on United States Treasury zero coupon issues with remaining terms similar to the expected term on the options. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore used an expected dividend yield of zero in the option-pricing model. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data was used to estimate pre-vesting option forfeitures and stock-based compensation expense was recorded only for those awards that are expected to vest. All share based payment awards are recognized on a straight-line basis over the requisite service periods of the awards.

The assumptions used to value option grants for the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006 are as follows: S tock O ption Plan 2008 2007 2006

The weighted-average fair value of options granted during the fiscal years ended January 2, 2009, December 28, 2007 and December 29, 2006 were $12.82, $8.48 and $7.47, respectively.

The employee does not need to make a contribution to the plan to be eligible for the Company’s 7% contribution. To be eligible under the plan, an employee must be at least 21 years of age and be either a full-time or part-time salaried employee. The 7% Company contribution will vest 20% per year for the first 5 years of employment and then immediately thereafter.

Total rent expense from property leases in 2008, 2007, and 2006 was $5,110,000, $4,996,000, and $4,804,000, respectively. Total expense from other operating leases and commitments in 2008, 2007, and 2006 was $1,477,000, $1,016,000, and $938,000, respectively. In July, 2008, the Company was served with a writ by a former client. The writ did not articulate a claim. The Company met with the former client in November of 2008 and again in January of 2009 and learned in those discussions of potential claims against the Company related to an adverse verdict against the former client. The adverse verdict is currently under appeal. The former client claims that this adverse verdict was due to the testimony delivered by one of the Company’s employees. Given the uncertainty as to whether the claimant will incur a loss (it may prevail on appeal), whether it will choose to pursue one or more claims against the Company and the nature of the potential claims against the Company, an estimated loss cannot be determined at this time. The Company believes it has a strong defense against all such potential claims and intends to vigorously defend itself. Further, the Company believes that some of the potential claims would be covered by insurance. Although the Company’s ultimate liability in this matter (if any) cannot be determined, based upon information currently available, the Company believes the ultimate resolution of these potential claims will not have a material adverse effect on its financial condition, results of operations or liquidity.

Exhibit 10.28 EXPONENT, INC. 2008 EMPLOYEE STOCK PURCHASE PLAN 1. ESTABLISHMENT OF PLAN Exponent, Inc. (the “Company”) adopted this plan in 2008 to grant options for the purchase of shares (“Shares”) of the Company’s Common Stock to eligible employees of the Company and Subsidiaries (as hereinafter defined) pursuant to this Employee Stock Purchase Plan (the “Plan”). For purposes of this Plan, “parent corporation” and “Subsidiary” (collectively, “Subsidiaries”) shall have the same meanings as “parent corporation” and “subsidiary corporation” in Section 424, of the Internal Revenue Code of 1986, as amended (the “Code”). The Company intends that the Plan shall qualify as an “employee stock purchase plan” under Section 423 of the Code (including any amendments or replacements of such section), and the Plan shall be so construed. Any term not expressly defined in the Plan but defined for purposes of Section 423 of the Code shall have the same definition in this Plan. A total of 200,000 Shares of Common Stock may be issued under the Plan. Such number shall be subject to adjustments effected in accordance with Section 14 of the Plan. 2. PURPOSES The purpose of the Plan is to provide employees of the Company and any Subsidiary designated by the Company’s Board of Directors (the “Board”) as one whose employees are eligible to participate in the Plan with a convenient means to acquire an equity interest in the Company through payroll deductions, to enhance such employees’ sense of participation in the affairs of the Company and Subsidiaries, and to provide an incentive for continued employment. 3. ADMINISTRATION (a) The Plan is administered by the Board or by a committee designated by the Board (in which event all references herein to the Board shall be to the committee). Subject to the provisions of the Plan and the limitations of Section 423 of the Code or any successor provision in the Code, all questions of interpretation or application of the Plan shall be determined by the Board and its decisions shall be final and binding upon all participants. Members of the Board shall receive no compensation for their services in connection with the administration of the Plan, other than standard fees as established from time to time by the Board of Directors of the Company for services rendered by Board members serving on Board committees. All expenses incurred in connection with the administration of the Plan shall be paid by the Company.

(v) To adopt rules and procedures (including sub-plans and/or special provisions) relating to the operation and administration of the Plan to permit participation in the Plan by employees who are foreign nationals or employed outside the United States; and (vi) Generally, to exercise such powers and to perform such acts it deems necessary, desirable, convenient or expedient to promote the best interests of the Company and its Subsidiaries and to carry out that intent that the Plan be treated as an “employee stock purchase plan” under Section 423 of the Code. 4. ELIGIBILITY Any employee of the Company or any of its Subsidiaries whom the Board designates as a participating Subsidiary (a “Designated Subsidiary”) is eligible to participate in an Offering Period (as hereinafter defined) under the Plan except the following: (a) employees who are not employed by the Company or a Designated Subsidiary on a date specified by the Board before the beginning of such Offering Period; (b) employees who are customarily employed for less than 20 hours per week; (c) employees who are customarily employed for less than 5 months in a calendar year; (d) employees who, together with any other person whose stock would be attributed to such employee pursuant to Section 425(d) of the Code, own stock or hold options to purchase stock or who, as a result of being granted an option under the Plan with respect to such Offering Period, would own stock or hold options to purchase stock possessing 5 percent or more of the total combined voting power or value of all classes of stock of the Company or any of its Subsidiaries; and (e) individuals who provide services to the Company or a Designated Subsidiary as independent contractors who are reclassified as common law employees for any reason except for federal income and employment tax purposes. 5. OFFERING PERIODS; OFFERING DATES; AND PURCHASE DATES (a) Each Offering Period under the Plan (each an “Offering Period”) shall be of the duration provided for or permitted herein. The first trading day (a day on which the Common Stock trades on the principal exchange or system on which the Common Stock is listed) of each Offering Period is referred to as the “Offering Date.” The Board may but need not provide for multiple purchases within a single Offering Period. The Board shall have the power to change the duration of Offering Periods without stockholder approval. The last trading day of each Offering Period (or in the case of an Offering Period encompassing multiple purchases, each such purchase period) is hereinafter referred to as the “Purchase Date.” (b) Subject to Section 5(c) below, each Offering Period shall be of three months’ duration commencing on the first business day of each fiscal quarter and ending on the last business day of the fiscal quarter, and shall have a single Purchase Date. (c) Notwithstanding 5(b) above and the other provisions of the Plan, the Board of Directors may, but need not, vary the terms and structure of the Offering Periods under this Plan, on such basis as it shall determine in its sole discretion (including without limitation, the length of each Offering Period and Offering Periods during which more than one Purchase Date shall occur; provided however that no Offering Period may have a duration in excess of twenty-seven (27) months (or such longer period as may be permitted under Code Section 423). 6. PARTICIPATION IN THE PLAN An eligible employee may become a participant in an Offering Period under the Plan if (a) as of the Offering Date with respect to the Offering Period he or she satisfies the eligibility requirements set forth above, and 2

(b) prior to such Offering Date (at such time and in such manner as may be specified with respect to such Offering Period) he or she delivers to the Company or its authorized representative a subscription agreement indicating his or her desire to enroll in the Offering Period and authorizing payroll deductions in a manner consistent with Section 9 below. An eligible employee who does not timely deliver a subscription agreement by the date specified in advance of the applicable Offering Date shall not participate in that Offering Period and shall not participate in any subsequent Offering Period unless such employee enrolls in the Plan by timely delivering a subscription agreement to the Company or its representative prior the Offering Date of the applicable, subsequent Offering Period. Once an employee becomes a participant in an Offering Period, such employee will automatically participate in the Offering Period commencing immediately following the last day of that Offering Period unless the employee withdraws from the Plan or terminates further participation in the Offering Period as set forth in Section 11 below. Such participant is not required to file any additional subscription agreements in order to continue participation in the Plan with respect to subsequent Offering Periods. Any participant who has not withdrawn from the Plan pursuant to Section 11 below will automatically be reenrolled in the Plan and granted a new option on the Offering Date of the next Offering Period. 7. GRANT OF OPTION (a) Each employee enrolled in an Offering Period will be granted on the Offering Date an option to purchase on each Purchase Date up to that number of Shares determined by dividing the amount accumulated in such employee’s payroll deduction account during such Offering Period by the Purchase Price (as defined in Section 8 below) applicable to that Offering Period. (b) In no event, however, shall the number of Shares of the Company’s Common Stock subject to any option granted pursuant to this Plan exceed the limitations set forth in Section 10 below. The Purchase Price and fair market value of a Share shall be determined as provided in Section 8 hereof. 8. PURCHASE PRICE The “Purchase Price” per Share at which a Share will be sold in any Offering Period shall be ninety-five percent (95%) of the fair market value on the applicable Purchase Date. For purposes of the Plan, the term “fair market value” on a given date shall mean: (a) the closing price on the Purchase Date of a Share as reported on the Nasdaq Stock Market (or any other exchange or market quotation system that is then the primary exchange or market on which the Common Stock trades), (b) if the relevant date does not fall on a trading day, the closing price of a Share as of the last preceding day on which the Common Stock traded, or (c) such other value as the Board determines in its good faith judgment to be a reasonable valuation for a Share as of such date. 3

9. PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF SHARES (a) The aggregate purchase price of the Shares is accumulated by regular payroll deductions made during each Offering Period. The deductions are made as a percentage of the employee’s compensation in one percent (1%) increments not less than one percent (1%) nor greater than fifteen percent (15%). Compensation shall mean all base straight-time gross earnings including commissions, overtime and paidtime off but exclusive of shift premiums, incentive compensation, bonuses, any amounts relating to Company equity awards, and other compensation not listed above; provided, however, that for purposes of determining a participant’s compensation, any election by such participant to reduce his or her regular cash remuneration under Sections 125 or 401(k) of the Code shall be treated as if the participant did not make such election. Payroll deductions shall commence on the first payroll date following the Offering Date and shall continue until the last payroll date immediately preceding the Purchase Date unless sooner altered or terminated as provided in the Plan. (b) Except pursuant to a withdrawal from the Plan under Section 11 below (in which case all payroll deductions shall cease), a participant may not change his or her rate of payroll deductions during an Offering Period. A participant may increase or decrease the rate of payroll deductions for any subsequent Offering Period by filing with the Administrator a new authorization for payroll deductions on a date specified by the Board prior to the beginning of such Offering Period. (c) All payroll deductions made for a participant are credited to his or her account under the Plan and are deposited with the general funds of the Company. No interest accrues on the payroll deductions. All payroll deductions received or held by the Company may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. (d) On each Purchase Date, so long as the Plan remains in effect and provided that the participant has not withdrawn from that Offering Period under the Plan in accordance with the provisions of Section 11 below before that date, the Company shall apply the funds then in the participant’s account to the purchase of whole Shares reserved under the option granted to such participant with respect to the Offering Period to the extent that such option is exercisable on the Purchase Date. The Purchase Price per Share shall be as specified in Section 8 of the Plan. Any cash remaining in a participant’s account after such purchase of Shares shall be refunded (without interest) to such participant in cash; provided, however, that any amount remaining in such participant’s account on a Purchase Date which is less than the amount necessary to purchase a full Share of Common Stock of the Company shall be carried forward, without interest, into the next Offering Period (or in the event of an Offering Period during which multiple purchase will occur, into the next applicable purchase period within the Offering Period). In the event that the Plan has been oversubscribed as provided in Section 10(c), all funds not used to purchase Shares on the Purchase Date shall be returned to the participant (without interest). No Shares shall be purchased on a Purchase Date on behalf of any employee whose participation in the Plan has terminated prior to such Purchase Date. (e) As promptly as practicable after the Purchase Date, the Company shall arrange the delivery to each participant, as appropriate, of a certificate representing the Shares purchased upon exercise of his option; provided that the Company may deliver certificates to a broker or brokers that hold such certificate in street name for the benefit of each such participant. (f) During a participant’s lifetime, such participant’s option to purchase Shares hereunder is exercisable only by him or her. The participant will have no interest or voting right in Shares covered by his or her option until such option has been exercised. Shares to be delivered to a participant under the Plan will be registered in the name of the participant or in the name of the participant and his or her spouse provided that shares may be registered to a broker or brokers that hold such shares in street name for the benefit of each participant. 10. LIMITATIONS ON SHARES TO BE PURCHASED (a) No employee shall be entitled to purchase Shares under the Plan at a rate which, when aggregated with his or her rights to purchase Shares of Common Stock under all other employee stock purchase plans of the Company or any Subsidiary, exceeds $25,000 in fair market value, determined as of the date such right is granted (or such other limit as may be imposed by the Code) for each calendar year in which the employee participates in the Plan. 4

(b) Subject to Sections 9(a), 10(a) and 14(a) of the Plan, the maximum number of Shares that a participant may purchase on any single Purchase Date shall not exceed 2,500 Shares (the “Maximum Share Amount”); provided that prior to the commencement of any Offering Period, the Board may, in its sole discretion and without stockholder approval, change the Maximum Share Amount with respect to that Offering Period. If a new Maximum Share Amount is set, then all participants must be notified of such Maximum Share Amount prior to the commencement of the next Offering Period. Once a Maximum Share Amount is set, it shall continue to apply in respect of all succeeding Purchase Dates and Offering Periods unless revised by the Board as set forth above. (c) If the number of Shares to be purchased on a Purchase Date by all employees participating in the Plan exceeds the number of Shares then available for issuance under the Plan, the Company will make a pro rata allocation of the remaining Shares in as uniform a manner as shall be practicable and as the Board shall determine to be equitable. In such event, the Company shall give written notice of such reduction of the number of Shares to be purchased under a participant’s option to each employee affected thereby. (d) Any payroll deductions accumulated in a participant’s account which are not used to purchase stock due to the limitations in this Section 10 shall be returned to the participant (without interest) as soon as practicable after the end of the Offering Period in the manner set forth in Section 9(d). 11. WITHDRAWAL (a) Each participant may withdraw from an Offering Period under the Plan by signing and delivering to the Administrator notice on a form provided for such purpose. Such withdrawal may be elected at any time prior to the end of an Offering Period at such time and in such manner as the Board specifies. (b) Upon withdrawal from the Plan, the accumulated payroll deductions shall be returned (without interest) to the withdrawn employee and his or her interest in the Plan shall terminate. In the event an employee voluntarily elects to withdraw from the Plan, he or she may not resume his or her participation in the Plan during the same Offering Period, but he or she may participate in any Offering Period under the Plan which commences on a date subsequent to such withdrawal by filing a new authorization for payroll deductions in the same manner as set forth in Section 6 above for initial participation in the Plan. 12. TERMINATION OF EMPLOYMENT Termination of a participant’s employment for any reason, including retirement or death, or the failure of a participant to remain an eligible employee as set forth in Section 4 terminates his or her participation in the Plan immediately. In such event, the payroll deductions credited to the participant’s account will be returned to him or her or, in the case of his or her death, to his or her legal representative. For this purpose, an employee will not be deemed to have terminated employment or failed to remain in the continuous employ of the Company in the case of sick leave, military leave, or any other leave of absence approved by the Board of Directors of the Company; provided that such leave is for a period of not more than ninety (90) days or, if such leave is longer than ninety (90) days, reemployment upon the expiration of such leave is guaranteed by contract or statute. 13. RETURN OF PAYROLL DEDUCTIONS In the event an employee’s interest in the Plan is terminated by withdrawal, termination of employment or otherwise, or in the event the Plan is terminated by the Board, the Company shall promptly deliver to the employee all payroll deductions credited to his or her account. No interest shall accrue on the payroll deductions of a participant in the Plan. 5

14. CAPITAL CHANGES Subject to any required action by the stockholders of the Company, the number of Shares covered by each option under the Plan which has not yet been exercised, the Maximum Share Amount set forth in Section 10(b) above, and the number of Shares which have been authorized for issuance under the Plan but have not yet been placed under option (collectively, the “Reserves”), as well as the price per Share covered by each option under the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split or the payment of a stock dividend (but only on the Common Stock) or any other increase or decrease in the number of Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an option. In the event of the proposed dissolution or liquidation of the Company, each Offering Period will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board. In such event, the Board may, in the exercise of its sole discretion in such instances, declare that the options under the Plan shall terminate as of a date fixed by the Board and give each participant the right to exercise his or her option as to all of the optioned stock. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation, each option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation, unless the Board determines, in the exercise of its sole discretion and in lieu of such assumption or substitution, that the participant shall have the right to exercise the option as to all of the optioned Shares. If the Board makes an option exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Board shall notify the participant that the option shall be fully exercisable on a date specified in such notice, and the option will terminate upon the expiration of such period. The Board may, if it so determines in the exercise of its sole discretion, also make provision for adjusting the Reserves, as well as the price per Share covered by each outstanding option, in the event that the Company effects one or more reorganizations, recapitalizations, rights offerings or other increases or reductions of Shares of its outstanding Common Stock, and in the event of the Company being consolidated with or merged into any other corporation. 15. NONASSIGNABILITY Neither payroll deductions credited to a participant’s account nor any rights with regard to the exercise of an option or to receive Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 22 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect. 16. REPORTS Individual accounts will be maintained for each participant in the Plan. Each participant shall receive any reports required to be delivered by applicable law as well as, after the end of each Offering Period, a report of his account setting forth the total payroll deductions accumulated, the number of Shares purchased, the per Share price thereof and the remaining cash balance, if any, carried forward to the next Offering Period or Offering Period, as the case may be. 17. NOTICE OF DISPOSITION Each participant shall notify the Company if the participant disposes of any of the Shares purchased in any Offering Period pursuant to this Plan if such disposition occurs within two years from the Offering Date or within one (1) year from the Purchase Date on which such Shares were purchased (the “Notice Period”). Unless such participant is disposing of any of such Shares during the Notice Period, such participant shall keep the certificates 6

representing such Shares in his or her name (and not in the name of a nominee) during the Notice Period. The Company may, at any time during the Notice Period, place a legend or legends on any certificate representing Shares acquired pursuant to the Plan requesting the Company’s transfer agent to notify the Company of any transfer of the Shares. The obligation of the participant to provide such notice shall continue notwithstanding the placement of any such legend on certificates. 18. NO RIGHTS TO CONTINUED EMPLOYMENT Neither this Plan nor the grant of any option hereunder shall confer any right on any employee to remain in the employ of the Company or any Subsidiary or restrict the right of the Company or any Subsidiary to terminate such employee’s employment. 19. EQUAL RIGHTS AND PRIVILEGES All participants in an Offering Period shall have the same rights and privileges with respect to their participation in the Plan for that Offering Period, in accordance with Section 423 of the Code and the related regulations (and any successor provisions). Any provision of the Plan, a specific Offering Period or an option granted under the Plan which is inconsistent with this Section 19 shall without further act or amendment by the Company or the Board be reformed, if possible, to the extent necessary to render such provision in compliance with the requirements of Section 423 of the Code, or shall otherwise be deleted, and the remainder of the terms of the Plan, an Offering Period and/or an option shall not be affected. 20. NOTICES All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 21. DESIGNATION OF BENEFICIARY (a) A participant may file a written designation of a beneficiary who is to receive any Shares and cash, if any, from the participant’s account under the Plan in the event of such participant’s death subsequent to the end of an Offering Period but prior to delivery to him of such Shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any cash from the participant’s account under the Plan in the event of such participant’s death prior to a Purchase Date. (b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company shall deliver such Shares or cash to the executor or administrator of the estate of the participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such Shares or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 22. CONDITIONS UPON ISSUANCE OF SHARES Shares shall not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such Shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. The Company shall have no liability for failure to issue any Shares under this Plan in the event that such issuance cannot be accomplished in compliance with all applicable laws. 7

The Board of Directors of the Company may at any time amend or terminate the Plan, except that any such termination cannot affect options previously granted under the Plan, nor may any amendment make any change in an option previously granted which would adversely affect the right of any participant; provided that if the Board determines that a change in applicable accounting rules or a change in applicable laws, renders an amendment or termination desirable, then the Board may approve such an amendment or termination. The Board may not amend the Plan without approval of the stockholders of the Company obtained in accordance with Section 21 hereof within 12 months of the adoption of such amendment (or earlier if required by Section 21) if such amendment would: (a) Increase the number of Shares that may be issued under the Plan; or (b) Expand the designation of the employees (or class of employees) eligible for participation in the Plan. 8 Exhibit 10.29 EXPONENT, INC. 2008 EQUITY INCENTIVE PLAN 1.

(mm) “Termination of Employment” shall mean ceasing to be an Employee, Consultant or Director, as determined in the sole discretion of the Administrator. However, for Incentive Stock Option purposes, Termination of Employment will occur when the Awardee ceases to be an employee (as determined in accordance with Section 3401(c) of the Code and the regulations promulgated thereunder) of the Company or one of its Subsidiaries.

Administration of the Plan. (a) Procedure. i. Multiple Administrative Bodies. The Plan shall be administered by a Committee and/or their delegates; provided however that any delegation of authority to any Committee or delegate does not diminish the authority of the Board to administer the Plan should it deem it appropriate. ii. Section 162. To the extent that the Administrator determines it to be desirable to qualify Awards granted hereunder as “performance-based compensation” within the meaning of Section 162(m) of the Code, Awards to “covered employees” within the meaning of Section 162(m) of the Code or Employees that the Committee determines may be “covered employees” in the future shall be made by a Committee of two or more “outside directors” within the meaning of Section 162(m) of the Code. iii.

iii. to determine the type of Award to be granted to the selected Employees, Consultants and Directors; iv. to approve forms of Award Agreements for use under the Plan; v. to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Award granted hereunder. Such terms and conditions include, but are not limited to, the exercise and/or purchase price (if applicable), the time or times when an Award may be exercised (which may or may not be based on performance criteria), the vesting schedule, any vesting and/or exercisability acceleration or waiver of forfeiture restrictions, the acceptable forms of consideration, the term, and any restriction or limitation regarding any Award or the Shares relating thereto, based in each case on such factors as the Administrator, in its sole discretion, shall determine and may be established at the time an Award is granted or thereafter; vi. to correct administrative errors; vii. to construe and interpret the terms of the Plan (including sub-plans and Plan addenda) and Awards granted pursuant to the Plan; viii. to adopt rules and procedures relating to the operation and administration of the Plan to accommodate the specific requirements of local laws and procedures. Without limiting the generality of the foregoing, the Administrator is specifically authorized (A) to adopt the rules and procedures regarding the conversion of local currency, withholding procedures and handling of stock certificates which vary with local requirements and (B) to adopt sub-plans and Plan addenda as the Administrator deems desirable, to accommodate foreign laws, regulations and practice; ix. to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to subplans and Plan addenda; x. to modify or amend each Award, including, but not limited to, the acceleration of vesting and/or exercisability, provided, however, that any such amendment is subject to Section 15 of the Plan and except as set forth in that Section, may not impair any outstanding Award unless agreed to in writing by the Participant; xi. to allow Participants to satisfy withholding tax amounts by electing to have the Company withhold from the Shares to be issued upon exercise of an Option or vesting of a Stock Award that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined in such manner and on such date that the Administrator shall determine or, in the absence of provision otherwise, on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may provide; xii. to authorize conversion or substitution under the Plan of any or all stock options, stock appreciation rights or other stock awards held by service providers of an entity acquired by the Company (the “Conversion Awards”). Any conversion or substitution shall be effective as of the close of the merger, acquisition or other transaction. The Conversion Awards may be Nonstatutory Stock Options or Incentive Stock Options, as determined by the Administrator, with respect to options granted by the acquired entity; provided, however, that with respect to the conversion of stock appreciation rights in the acquired entity, the Conversion Awards shall be Nonstatutory Stock Options. Unless otherwise determined by the Administrator at the time of conversion or substitution, all Conversion Awards shall have the same terms and conditions as Awards generally granted by the Company under the Plan; 6

xiii. to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Administrator; xiv. to impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by a Participant or other subsequent transfers by the Participant of any Shares issued as a result of or under an Award, including without limitation, (A) restrictions under an insider trading policy or under any other Company policy relating to Company stock and stock ownership and (B) restrictions as to the use of a specified brokerage firm for such resales or other transfers; xv. to provide, either at the time an Award is granted or by subsequent action, that an Award shall contain as a term thereof, a right, either in tandem with the other rights under the Award or as an alternative thereto, of the Participant to receive, without payment to the Company, a number of Shares, cash or a combination thereof, the amount of which is determined by reference to the value of the Award; and xvi. to make all other determinations deemed necessary or advisable for administering the Plan and any Award granted hereunder. (c) Effect of Administrator’s Decision. All decisions, determinations and interpretations by the Administrator regarding the Plan, any rules and regulations under the Plan and the terms and conditions of any Award granted hereunder, shall be final and binding on all Participants and on all other persons. The Administrator shall consider such factors as it deems relevant, in its sole and absolute discretion, to making such decisions, determinations and interpretations including, without limitation, the recommendations or advice of any officer or other employee of the Company and such attorneys, consultants and accountants as it may select. 5. Eligibility. Awards may be granted to Employees, Consultants and Directors of the Company or any of its Affiliates; provided that Incentive Stock Options may be granted only to Employees of the Company or of a Subsidiary of the Company. 6. Term of Plan. The Plan shall become effective on the Effective Date. It shall continue in effect for a term of ten (10) years from the later of the Effective Date or the date any amendment to add shares to the Plan is approved by stockholders of the Company unless terminated earlier under Section 15 of the Plan. 7. Term of Award. The term of each Award shall be determined by the Administrator and stated in the Award Agreement. In the case of an Option, the term shall be ten (10) years from the Grant Date or such shorter term as may be provided in the Award Agreement; provided that an Incentive Stock Option granted to an Employee who on the Grant Date owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Subsidiary shall have a term of no more than five (5) years from the Grant Date; and provided further that the term may be ten and one-half (101/2) years (or a shorter period) in the case of Options granted to Employees in certain jurisdictions outside the United States as determined by the Administrator. 8. Options. The Administrator may grant an Option or provide for the grant of an Option, either from time to time in the discretion of the Administrator or automatically upon the occurrence of specified events, including, without limitation, the achievement of performance goals, the satisfaction of an event or condition within the control of the Awardee or within the control of others. 7

(b) Exercise Price. The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be determined by the Administrator, subject to the following: i. In the case of an Incentive Stock Option, the per Share exercise price shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the Grant Date; provided however, that in the case of an Incentive Stock Option granted to an Employee who on the Grant Date owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Subsidiary, the per Share exercise price shall be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the Grant Date. ii. In the case of a Nonstatutory Stock Option, the per Share exercise price shall be no less than one hundred percent (100%) of the Fair Market Value per Share on the Grant Date. iii. Notwithstanding the foregoing, at the Administrator’s discretion, Conversion Awards may be granted in substitution and/or conversion of options of an acquired entity, with a per Share exercise price of less than 100% of the Fair Market Value per Share on the date of such substitution and/or conversion. (c) Vesting Period and Exercise Dates. Options granted under this Plan shall vest and/or be exercisable at such time and in such installments during the period prior to the expiration of the Option’s term as determined by the Administrator. The Administrator shall have the right to make the timing of the ability to exercise any Option granted under this Plan subject to continued employment, the passage of time and/or such performance requirements as deemed appropriate by the Administrator, or to grant fully vested Options. At any time after the grant of an Option, the Administrator may reduce or eliminate any restrictions surrounding any Participant’s right to exercise all or part of the Option. (d) Form of Consideration. The Administrator shall determine the acceptable form of consideration for exercising an Option, including the method of payment, either through the terms of the Option Agreement or at the time of exercise of an Option. Acceptable forms of consideration may include: i. cash; ii. check or wire transfer (denominated in U.S. Dollars); iii. subject to the Company’s discretion to refuse for any reason and at any time to accept such consideration and subject to any conditions or limitations established by the Administrator, other Shares held by the Participant which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised; iv. consideration received by the Company under a broker-assisted sale and remittance program acceptable to the Administrator; v. cashless “net exercise” arrangement pursuant to which the Company will reduce the number of Shares issued upon exercise by the largest whole number of Shares having an aggregate Fair Market Value that does not exceed the aggregate exercise price; provided that the Company shall accept a cash or other payment from the Participant to the extent of any remaining balance of the exercise price not satisfied by such reduction in the number of whole Shares to be issued; 8

vi. such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws; or vii. any combination of the foregoing methods of payment. (e) Effect of Termination on Options i. Generally. Unless otherwise provided for by the Administrator, upon an Awardee’s Termination of Employment other than as a result of circumstances described in Sections 8(f)(ii), (iii) and (iv) below, all outstanding Options granted to such Awardee that were vested and exercisable as of the date of the Awardee’s Termination of Employment may be exercised by the Awardee until the earlier of (A) three (3) months following Awardee’s Termination of Employment or (B) the expiration of the term of such Option; provided, however, that the Administrator may in the Option Agreement specify a period of time (but not beyond the expiration date of the Option) following Termination of Employment during which the Awardee may exercise the Option as to Shares that were vested and exercisable as of the date of Termination of Employment. To the extent such a period following Termination of Employment is specified, the Option shall automatically terminate at the end of such period to the extent the Awardee has not exercised it within such period. ii. Disability of Awardee. Unless otherwise provided for by the Administrator, upon an Awardee’s Termination of Employment as a result of the Awardee’s disability, including Total and Permanent Disability, all outstanding Options granted to such Awardee that were vested and exercisable as of the date of the Awardee’s Termination of Employment may be exercised by the Awardee until the earlier of (A) twelve (12) months following Awardee’s Termination of Employment as a result of Awardee’s disability, including Total and Permanent Disability or (B) the expiration of the term of such Option. If the Participant does not exercise such Option within the time specified, the Option (to the extent not exercised) shall automatically terminate. iii. Death of Awardee. Unless otherwise provided for by the Administrator, upon an Awardee’s Termination of Employment as a result of the Awardee’s death, all outstanding Options granted to such Awardee that were vested and exercisable as of the date of the Awardee’s death may be exercised until the earlier of (A) twelve (12) months following the Awardee’s death or (B) the expiration of the term of such Option. If an Option is held by the Awardee when he or she dies, such Option may be exercised, to the extent the Option is vested and exercisable, by the beneficiary designated by the Awardee (as provided in Section 16 of the Plan), the executor or administrator of the Awardee’s estate or, if none, by the person(s) entitled to exercise the Option under the Awardee’s will or the laws of descent or distribution; provided that the Company need not accept exercise of an Option by such beneficiary, executor or administrator unless the Company has satisfactory evidence of such person’s authority to act as such. If the Option is not so exercised within the time specified, such Option (to the extent not exercised) shall automatically terminate. The Awardee’s service shall be deemed to have terminated on account of death if the Awardee dies within three (3) months (or such longer period as determined by the Administrator, in its discretion) after the Awardee’s Termination of Employment. iv. Termination for Cause. The Administrator has the authority to cause all outstanding Awards held by an Awardee to terminate immediately in their entirety (including as to vested Options) upon first notification to the Awardee of the Awardee’s Termination of Employment for Cause. If an Awardee’s employment or consulting relationship with the Company is suspended pending an investigation of whether the Awardee shall be terminated for Cause, the Administrator has the authority to cause all the Awardee’s rights under all outstanding Awards to be suspended during the investigation period in which event the Awardee shall have no right to exercise any outstanding Awards. 9

v. Other Terminations of Employment. The Administrator may provide in the applicable Option Agreement for different treatment of Options upon Termination of Employment of the Awardee than that specified above. vi. Extension of Exercise Period. The Administrator shall have full power and authority to extend the period of time for which an Option is to remain exercisable following an Awardee’s Termination of Employment from the periods set forth in Sections 8(f)(i), (ii) and (iii) above or in the Option Agreement to such greater time as the Board shall deem appropriate, provided that in no event shall such Option be exercisable later than the date of expiration of the term of such Option as set forth in the Option Agreement. vii. Extension if Exercise Prevented by Law. Notwithstanding the foregoing, other than a termination for Cause, if a sale within the applicable time periods set forth in Section 8(f) above or in the Option Agreement is prevented by Section 18 below, the Option shall remain exercisable until thirty (30) days after the date the Awardee is notified by the Company that the Option is exercisable, but in any event no later than the Option expiration date. viii. Extension if Subject to Section 16(b). Notwithstanding the foregoing, other than a termination for Cause, if a sale within the applicable time periods set forth in Section 8(f) above or in the Option Agreement would subject the Awardee to a suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to occur of (i) the tenth (10th) day following the date on which a sale of shares by the Awardee would no longer be subject to suit, (ii) the one hundred ninetieth (190th) day after Awardee’s Termination of Employment, or (iii) the Option expiration date. (f) Leave of Absence. The Administrator shall have the discretion to determine whether and to what extent the vesting of Options shall be tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any leave that is not a leave required to be provided to the Awardee under Applicable Law. In the event of military leave, vesting shall toll during any unpaid portion of such leave, provided that, upon an Awardee’s returning from military leave (under conditions that would entitle him or her to protection upon such return under the Uniform Services Employment and Reemployment Rights Act), he or she shall be given vesting credit with respect to Options to the same extent as would have applied had the Awardee continued to provide services to the Company throughout the leave on the same terms as he or she was providing services immediately prior to such leave. 9. Incentive Stock Option Limitations/Terms. (a) Eligibility. Only employees (as determined in accordance with Section 3401(c) of the Code and the regulations promulgated thereunder) of the Company or any of its Subsidiaries may be granted Incentive Stock Options. (b) $100,000 Limitation. Notwithstanding the designation “Incentive Stock Option” in an Option Agreement, if and to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Awardee during any calendar year (under all plans of the Company and any of its Subsidiaries) exceeds U.S. $100,000, such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 9(b), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the Grant Date. (c) Transferability. An Incentive Stock Option may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner by the Awardee otherwise than by will or the laws of descent and distribution, and, during the lifetime of such Awardee, may only be exercised by the Awardee. If the terms of an Incentive Stock Option are amended to permit transferability, the Option will be treated for tax purposes as a Nonstatutory Stock Option. The designation of a beneficiary by an Awardee will not constitute a transfer. 10

(d) Exercise Price. The per Share exercise price of an Incentive Stock Option shall be determined by the Administrator in accordance with Section 8(b)(i) of the Plan. (e) Other Terms. Option Agreements evidencing Incentive Stock Options shall contain such other terms and conditions as may be necessary to qualify, to the extent determined desirable by the Administrator, with the applicable provisions of Section 422 of the Code. 10. Exercise of Option. (a) Procedure for Exercise. i. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the respective Option Agreement. ii. An Option shall be deemed exercised when the Company receives (A) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Option; (B) full payment for the Shares with respect to which the related Option is exercised; and (C) payment of all applicable withholding taxes (if any). iii. An Option may not be exercised for a fraction of a Share. (b) Rights as a Stockholder. The Company shall issue (or cause to be issued) such Shares as administratively practicable after the Option is exercised. Shares issued upon exercise of an Option shall be issued in the name of the Participant or, if requested by the Participant, in the name of the Participant and his or her spouse. Unless provided otherwise by the Administrator or pursuant to this Plan, until the Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Shares subject to an Option, notwithstanding the exercise of the Option. 11. Stock Awards. (a) Stock Award Agreement. Each Stock Award Agreement shall contain provisions regarding (i) the number of Shares subject to such Stock Award or a formula for determining such number, (ii) the purchase price of the Shares, if any, and the means of payment for the Shares, (iii) the performance criteria (including Qualifying Performance Criteria), if any, and level of achievement versus these criteria that shall determine the number of Shares granted, issued, retainable and/or vested, (iv) such terms and conditions on the grant, issuance, vesting, settlement and/or forfeiture of the Shares as may be determined from time to time by the Administrator, (v) restrictions on the transferability of the Stock Award and (vi) such further terms and conditions in each case not inconsistent with this Plan as may be determined from time to time by the Administrator. (b) Restrictions and Performance Criteria. The grant, issuance, retention, settlement and/or vesting of each Stock Award or the Shares subject thereto may be subject to such performance criteria (including Qualifying Performance Criteria) and level of achievement versus these criteria as the Administrator shall determine, which criteria may be based on financial performance, personal performance evaluations and/or completion of service by the Awardee. Unless otherwise permitted in compliance with the requirements of Code Section 162(m) with respect to an Award intended to comply as “performance-based compensation” thereunder, the Committee shall establish the Qualifying Performance Criteria applicable to, and the formula for calculating the amount payable under, the Award no later than the earlier of (a) the date ninety (90) days after the commencement of the applicable performance period, or (b) the date on which 25% of the performance period has elapsed, and in any event at a time when the achievement of the applicable Qualifying Performance Criteria remains substantially uncertain. 11

(c) Forfeiture. Unless otherwise provided for by the Administrator, upon the Awardee’s Termination of Employment, the Stock Award and the Shares subject thereto shall be forfeited, provided that to the extent that the Participant purchased or earned any Shares, the Company shall have a right to repurchase the unvested Shares at such price and on such terms and conditions as the Administrator determines. (d) Rights as a Stockholder. Unless otherwise provided by the Administrator in the Award Agreement, the Participant shall have the rights equivalent to those of a stockholder and shall be a stockholder only after Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) to the Participant. Unless otherwise provided by the Administrator, a Participant holding Stock Units shall not be entitled to receive dividend payments or any credit therefor as if he or she was an actual stockholder. (e) Stock Appreciation Rights. i. General. Stock Appreciation Rights may be granted either alone, in addition to, or in tandem with other Awards granted under the Plan. The Board may grant Stock Appreciation Rights to eligible Participants subject to terms and conditions not inconsistent with this Plan and determined by the Board. The specific terms and conditions applicable to the Participant shall be provided for in the Stock Award Agreement. Stock Appreciation Rights shall be exercisable, in whole or in part, at such times as the Board shall specify in the Stock Award Agreement. ii. Exercise of Stock Appreciation Right. Upon the exercise of a Stock Appreciation Right, in whole or in part, the Participant shall be entitled to a payment in an amount equal to the excess of the Fair Market Value on the date of exercise of a fixed number of Shares covered by the exercised portion of the Stock Appreciation Right, over the Fair Market Value on the Grant Date of the Shares covered by the exercised portion of the Stock Appreciation Right (or such other amount calculated with respect to Shares subject to the Award as the Board may determine). The amount due to the Participant upon the exercise of a Stock Appreciation Right shall be paid in such form of consideration as determined by the Board and may be in cash, Shares or a combination thereof, over the period or periods specified in the Stock Award Agreement. A Stock Award Agreement may place limits on the amount that may be paid over any specified period or periods upon the exercise of a Stock Appreciation Right, on an aggregate basis or as to any Participant. A Stock Appreciation Right shall be considered exercised when the Company receives written notice of exercise in accordance with the terms of the Stock Award Agreement from the person entitled to exercise the Stock Appreciation Right. iii. Nonassignability of Stock Appreciation Rights. Except as determined by the Administrator, no Stock Appreciation Right shall be assignable or otherwise transferable by the Participant except by will or by the laws of descent and distribution. 12. Cash Awards. (a) Cash Award. Each Cash Award shall contain provisions regarding (i) the target and maximum amount payable to the Awardee as a Cash Award, (ii) the performance criteria and level of achievement versus these criteria which shall determine the amount of such payment, (iii) the period as to which performance shall be measured for establishing the amount of any payment, (iv) the timing of any payment earned by virtue of performance, (v) restrictions on the alienation or transfer of the Cash Award prior to actual payment, (vi) forfeiture provisions, and (vii) such further terms and conditions, in each case not inconsistent with the Plan, as may be determined from time to time by the Administrator. The maximum amount payable as a Cash Award may be a multiple of the target amount payable, but the maximum amount payable pursuant to that portion of a Cash Award granted under this Plan for any fiscal year to any Awardee that is intended to satisfy the requirements for “performance based compensation” under Section 162(m) of the Code shall not exceed U.S. $1,000,000. 12

(b) Performance Criteria. The Administrator shall establish the performance criteria and level of achievement versus these criteria which shall determine the target and the minimum and maximum amount payable under a Cash Award, which criteria may be based on financial performance and/or personal performance evaluations. The Committee may specify the percentage of the target Cash Award that is intended to satisfy the requirements for “performance-based compensation” under Section 162(m) of the Code. Notwithstanding anything to the contrary herein, the performance criteria for any portion of a Cash Award that is intended to satisfy the requirements for “performance-based compensation” under Section 162(m) of the Code shall be a measure established by the Committee based on one or more Qualifying Performance Criteria selected by the Committee and specified in writing not later than the earlier of (a) the date ninety (90) days after the commencement of the applicable performance period, or (b) the date on which 25% of the performance period has elapsed, and in any event at a time when the achievement of the applicable Qualifying Performance Criteria remains substantially uncertain. (c) Timing and Form of Payment. The Administrator shall determine the timing of payment of any Cash Award. The Administrator may provide for or, subject to such terms and conditions as the Administrator may specify, may permit an Awardee to elect for the payment of any Cash Award to be deferred to a specified date or event. The Administrator may specify the form of payment of Cash Awards, which may be cash or other property, or may provide for an Awardee to have the option for his or her Cash Award, or such portion thereof as the Administrator may specify, to be paid in whole or in part in cash or other property. (d) Termination of Employment. The Administrator shall have the discretion to determine the effect a Termination of Employment due to (i) disability, (ii) death or (iii) otherwise shall have on any Cash Award. 13. Other Provisions Applicable to Awards. (a) Non-Transferability of Awards. Unless determined otherwise by the Administrator, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner for value other than by beneficiary designation, will or by the laws of descent or distribution. Subject to Section 9(c), the Administrator may in its discretion make an Award transferable to an Awardee’s family member or any other person or entity as it deems appropriate. If the Administrator makes an Award transferable, either at the time of grant or thereafter, such Award shall contain such additional terms and conditions as the Administrator deems appropriate, and any transferee shall be deemed to be bound by such terms upon acceptance of such transfer. (b) Qualifying Performance Criteria. For purposes of this Plan, the term “Qualifying Performance Criteria” shall mean any one or more of the following performance criteria, either individually, alternatively or in any combination, applied to either the Company as a whole or to a business unit, Affiliate or business segment, either individually, alternatively or in any combination, and measured either annually or cumulatively over a period of years, on an absolute basis or relative to a pre-established target, to previous years’ results or to a designated comparison group, in each case as specified by the Administrator in the Award: (i) cash flow; (ii) earnings (including gross margin; earnings before interest, taxes, depreciation, amortization and stock-based compensation; earnings before taxes; and net earnings); (iii) earnings per share; (iv) stock price; (v) return on equity or average stockholders’ equity; (vi) total stockholder return; (vii) return on assets or net assets; (viii) return on investment; (ix) revenue before reimbursements; (x) income or net income; (xi) operating income or net operating income, in aggregate or per share; (xii) operating profit or net operating profit; (xiii) operating margin; (xiv) return on operating revenue; (xv) contract awards or backlog; (xvi) overhead or other expense reduction; (xvii) growth in stockholder value relative to the moving average of the S&P 500 Index or S&P SmallCap 600 Index; and (xviii) objective strategic plan development and implementation (including individual objective performance goals that relate to achievement of the Company’s or any business unit’s strategic plan). The Committee may appropriately adjust any evaluation of performance under a Qualifying Performance Criteria to exclude any of the following events that occurs during a performance period: (A) asset write-downs; (B) litigation or claim judgments or settlements; (C) the effect of changes in tax law, accounting principles or other such laws or provisions affecting reported results; (D) accruals for reorganization and restructuring programs; and (E) any gains or losses classified as extraordinary or as discontinued operations in the Company’s financial statements. 13

(c) Certification. Prior to the payment of any compensation under an Award intended to qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall certify the extent to which any Qualifying Performance Criteria and any other material terms under such Award have been satisfied (other than in cases where such relate solely to the increase in the value of the Common Stock). (d) Discretionary Adjustments Pursuant to Section 162(m). Notwithstanding satisfaction of any completion of any Qualifying Performance Criteria, to the extent specified at the time of grant of an Award to “covered employees” within the meaning of Section 162(m) of the Code, the number of Shares, Options or other benefits granted, issued, retainable and/or vested under an Award on account of satisfaction of such Qualifying Performance Criteria may be reduced by the Committee on the basis of such further considerations as the Committee in its sole discretion shall determine. (e) Tax Withholding Obligation. As a condition of the grant, issuance, vesting, exercise or settlement of an Award granted under the Plan, the Participant shall make such arrangements as the Administrator may require for the satisfaction of any applicable federal, state, local or foreign withholding tax obligations that may arise in connection with such grant, issuance, vesting, exercise or settlement of the Award. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. (f) Compliance with Section 409A. Notwithstanding anything to the contrary contained herein, to the extent that the Administrator determines that any Award granted under the Plan is subject to Code Section 409A and unless otherwise specified in the applicable Award Agreement, the Award Agreement evidencing such Award shall incorporate the terms and conditions necessary for such Award to avoid the consequences described in Code Section 409A(a)(1), and to the maximum extent permitted under Applicable Law (and unless otherwise stated in the applicable Award Agreement), the Plan and the Award Agreements shall be interpreted in a manner that results in their conforming to the requirements of Code Section 409A(a)(2), (3) and (4) and any Department of Treasury or Internal Revenue Service regulations or other interpretive guidance issued under Section 409A (whenever issued, the “Guidance”). Notwithstanding anything to the contrary in this Plan (and unless the Award Agreement provides otherwise, with specific reference to this sentence), to the extent that a Participant holding an Award that constitutes “deferred compensation” under Section 409A and the Guidance is a “specified employee” (also as defined thereunder), no distribution or payment of any amount shall be made before a date that is six (6) months following the date of such Participant’s “separation from service” (as defined in Section 409A and the Guidance) or, if earlier, the date of the Participant’s death. (g) Deferral of Award Benefits. The Administrator may in its discretion and upon such terms and conditions as it determines appropriate permit one or more Participants whom it selects to (a) defer compensation payable pursuant to the terms of an Award, or (b) defer compensation arising outside the terms of this Plan pursuant to a program that provides for deferred payment in satisfaction of such other compensation amounts through the issuance of one or more Awards. Any such deferral arrangement shall be evidenced by an Award Agreement in such form as the Administrator shall from time to time establish, and no such deferral arrangement shall be a valid and binding obligation unless evidenced by a fully executed Award Agreement, the form of which the Administrator has approved, including through the Administrator’s establishing a written program (the “Program”) under this Plan to govern the form of Award Agreements participating in such Program. Any such Award Agreement or Program shall specify the treatment of dividends or dividend equivalent rights (if any) that apply to Awards governed thereby, and shall further provide that any elections governing payment of amounts pursuant to such Program shall be in writing, shall be delivered to the Company or its agent in a form and manner that complies with Code Section 409A and the Guidance, and shall specify the amount to be distributed in settlement of the deferral arrangement, as well as the time and form of such distribution in a manner that complies with Code Section 409A and the Guidance. 14

14. Adjustments upon Changes in Capitalization, Dissolution, or Change In Control (a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each outstanding Award, the number of shares of Common Stock which have been authorized for issuance under the Plan, but as to which no Awards have yet been granted or which have been returned to the Plan upon cancellation, forfeiture or expiration of an Award, the price per Share subject to each such outstanding Award and each of the share limits set forth in Section 3(b), shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, payment of a dividend or distribution in a form other than stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of the shares of Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Award. (b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Participant as soon as practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised or the Shares subject thereto issued to the Awardee and unless otherwise determined by the Administrator, an Award will terminate immediately prior to the consummation of such proposed transaction. (c) Change in Control. In the event there is a Change in Control of the Company, as determined by the Board or a Committee, the Board or Committee may, in its discretion, (i) provide for the assumption or substitution of, or adjustment (including to the number and type of Shares and exercise or purchase price applicable) to, each outstanding Award; (ii) accelerate the vesting of Options and terminate any restrictions on Stock Awards; and/or (iii) provide for termination of Awards as a result of the Change in Control on such terms and conditions as it deems appropriate, including providing for the cancellation of Awards for a cash or other payment to the Participant. For purposes of this Section 14(c), an Award shall be considered assumed, without limitation, if, at the time of issuance of the stock or other consideration upon a Change in Control, as the case may be, each holder of an Award would be entitled to receive upon exercise of the Award the same number and kind of shares of stock or the same amount of property, cash or securities as such holder would have been entitled to receive upon the occurrence of the transaction if the holder had been, immediately prior to such transaction, the holder of the number of Shares covered by the Award at such time (after giving effect to any adjustments in the number of Shares covered by the Award as provided for in Section 14(a)); provided that if such consideration received in the transaction is not solely common stock of the successor corporation, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon exercise of the Award to be solely common stock of the successor corporation equal to the Fair Market Value of the per Share consideration received by holders of Common Stock in the transaction. The treatment of Cash Awards in a transaction governed by this Section 14(c) shall be governed by the applicable Award Agreement. 15. Amendment and Termination of the Plan. (a) Amendment and Termination. The Administrator may amend, alter or discontinue the Plan or any Award Agreement, but any such amendment shall be subject to approval of the stockholders of the Company in the manner and to the extent required by Applicable Law. To the extent required to comply with Section 162(m), the Company shall seek re-approval of the Plan from time to time by the stockholders. In addition, without limiting the foregoing, unless approved by the stockholders of the Company, no such amendment shall be made that would: i. increase the maximum number of Shares for which Awards may be granted under the Plan, other than an increase pursuant to Section 14 of the Plan; 15

Processed and formatted by SEC Watch - Visit SECWatch.com

ii. increase the share limits set forth in Section 3(b) or the cash limit set forth in Section 12(a); iii. reprice or otherwise reduce the exercise price of Options outstanding under the Plan, other than an adjustment provided for under Section 14 of the Plan; or iv. change the class of persons eligible to receive Awards under the Plan. (b) Effect of Amendment or Termination. No amendment, suspension or termination of the Plan shall impair the rights of any Award, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the Participant and the Company; provided further that the Administrator may amend an outstanding Award in order to conform it to the Administrator’s intent (in its sole discretion) that such Award not be subject to Code Section 409A(a)(1)(B). Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. (c) Effect of the Plan on Other Arrangements. Neither the adoption of the Plan by the Board or a Committee nor the submission of the Plan to the stockholders of the Company for approval shall be construed as creating any limitations on the power of the Board or any Committee to adopt such other incentive arrangements as it or they may deem desirable, including without limitation, the granting of restricted stock, stock options or cash bonuses otherwise than under the Plan, and such arrangements may be either generally applicable or applicable only in specific cases. The value of Awards granted pursuant to the Plan will not be included as compensation, earnings, salaries or other similar terms used when calculating an Awardee’s benefits under any employee benefit plan sponsored by the Company or any Subsidiary except as such plan otherwise expressly provides. 16. Designation of Beneficiary. (a) An Awardee may file a written designation of a beneficiary who is to receive the Awardee’s rights pursuant to Awardee’s Award or the Awardee may include his or her Awards in an omnibus beneficiary designation for all benefits under the Plan. To the extent that Awardee has completed a designation of beneficiary while employed with the Company, such beneficiary designation shall remain in effect with respect to any Award hereunder until changed by the Awardee to the extent enforceable under Applicable Law. (b) Such designation of beneficiary may be changed by the Awardee at any time by written notice. In the event of the death of an Awardee and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Awardee’s death, the Company shall allow the executor or administrator of the estate of the Awardee to exercise the Award, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may allow the spouse or one or more dependents or relatives of the Awardee to exercise the Award to the extent permissible under Applicable Law or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate. 17. No Right to Awards or to Employment. No person shall have any claim or right to be granted an Award and the grant of any Award shall not be construed as giving an Awardee the right to continue in the employ or service of the Company or its Affiliates. Further, the Company and its Affiliates expressly reserve the right, at any time, to dismiss any Employee, Consultant or Awardee at any time without liability or any claim under the Plan, except as provided herein or in any Award Agreement entered into hereunder. 16

18. Legal Compliance. Subject to Section 22, Shares shall not be issued pursuant to the exercise of an Option or Stock Award unless the exercise of such Option or Stock Award and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. 19. Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 20. Notice. Any written notice to the Company required by any provisions of this Plan shall be addressed to the Secretary of the Company and shall be effective when received. 21. Governing Law; Interpretation of Plan and Awards. (a) This Plan and all determinations made and actions taken pursuant hereto shall be governed by the substantive laws, but not the choice of law rules, of the state of Delaware. (b) In the event that any provision of the Plan or any Award granted under the Plan is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction, such provision shall be reformed, if possible, to the extent necessary to render it legal, valid and enforceable, or otherwise deleted, and the remainder of the terms of the Plan and/or Award shall not be affected except to the extent necessary to reform or delete such illegal, invalid or unenforceable provision. (c) The headings preceding the text of the sections hereof are inserted solely for convenience of reference, and shall not constitute a part of the Plan, nor shall they affect its meaning, construction or effect. (d) The terms of the Plan and any Award shall inure to the benefit of and be binding upon the parties hereto and their respective permitted heirs, beneficiaries, successors and assigns. (e) All questions arising under the Plan or under any Award shall be decided by the Administrator in its total and absolute discretion. In the event the Participant believes that a decision by the Administrator with respect to such person was arbitrary or capricious, the Participant may request arbitration with respect to such decision. The review by the arbitrator shall be limited to determining whether the Administrator’s decision was arbitrary or capricious. This arbitration shall be the sole and exclusive review permitted of the Administrator’s decision, and the Awardee shall as a condition to the receipt of an Award be deemed to explicitly waive any right to judicial review. (f) Notice of demand for arbitration shall be made in writing to the Administrator within thirty (30) days after the applicable decision by the Administrator. The arbitrator shall be selected from amongst those members of the Board who are neither Administrators nor Employees. If there are no such members of the Board, the arbitrator shall be selected by the Board. The arbitrator shall be an individual who is an attorney licensed to practice law in the State of Delaware. Such arbitrator shall be neutral within the meaning of the Commercial Rules of Dispute Resolution of the American Arbitration Association; provided, however, that the arbitration shall not be administered by the American Arbitration Association. Any challenge to the neutrality of the arbitrator shall be resolved by the arbitrator whose decision shall be final and conclusive. The arbitration shall be administered and conducted by the arbitrator pursuant to the Commercial Rules of Dispute Resolution of the American Arbitration Association. The decision of the arbitrator on the issue(s) presented for arbitration shall be final and conclusive and may be enforced in any court of competent jurisdiction. 17

22. Limitation on Liability. The Company and any Affiliate which is in existence or hereafter comes into existence shall not be liable to a Participant, an Employee, an Awardee or any other persons as to: (a) The Non-Issuance of Shares. The non-issuance or sale of Shares (including under Section 18 above) as to which the Company has been unable, or the Arbitration deems it infeasible, to obtain from any regulatory body having jurisdiction the authority deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any shares hereunder; and (b) Tax Consequences. Any tax consequence realized by any Participant, Employee, Awardee or other person due to the receipt, vesting, exercise or settlement of any Option or other Award granted hereunder or due to the transfer of any Shares issued hereunder. The Participant is responsible for, and by accepting an Award under the Plan agrees to bear, all taxes of any nature that are legally imposed upon the Participant in connection with an Award, and the Company does not assume, and will not be liable to any party for, any cost or liability arising in connection with such tax liability legally imposed on the Participant. In particular, Awards issued under the Plan may be characterized by the Internal Revenue Service (the “IRS”) as “deferred compensation” under the Code resulting in additional taxes, including in some cases interest and penalties. In the event the IRS determines that an Award constitutes deferred compensation under the Code or challenges any good faith characterization made by the Company or any other party of the tax treatment applicable to an Award, the Participant will be responsible for the additional taxes, and interest and penalties, if any, that are determined to apply if such challenge succeeds, and the Company will not reimburse the Participant for the amount of any additional taxes, penalties or interest that result. (c) Forfeiture. The requirement that Participant forfeit an Award, or the benefits received or to be received under an Award, pursuant to any Applicable Law. 23. Indemnification. In addition to such other rights of indemnification as they may have as members of the Board or officers or employees of the Company or an Affiliate, members of the Board and any officers or employees of the Company or an Affiliate to whom authority to act for the Board or the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in any such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at its own expense to handle and defend the same. 24. Unfunded Plan. Insofar as it provides for Awards, the Plan shall be unfunded. Although bookkeeping accounts may be established with respect to Awardees who are granted Stock Awards under this Plan, any such accounts will be used merely as a bookkeeping convenience. The Company shall not be required to segregate any assets which may at any time be represented by Awards, nor shall this Plan be construed as providing for such segregation, nor shall the Company nor the Administrator be deemed to be a trustee of stock or cash to be awarded under the Plan. Any liability of the Company to any Participant with respect to an Award shall be based solely upon any contractual obligations which may be created by the Plan; no such obligation of the Company shall be deemed to be secured by any pledge or other encumbrance on any property of the Company. Neither the Company nor the Administrator shall be required to give any security or bond for the performance of any obligation which may be created by this Plan. 18 Exhibit 10.30 EXPONENT, INC. 2008 EQUITY INCENTIVE PLAN STOCK OPTION AGREEMENT THIS STOCK OPTION AGREEMENT (the “Agreement”) dated [GRANT DATE] (“Grant Date”) between Exponent, Inc., a Delaware corporation (the “Company”), and [EMPLOYEE NAME] (“Optionee”), is entered into as follows: WITNESSETH: WHEREAS, the Company has established the 2008 Equity Incentive Plan (the “Plan”); and WHEREAS, the Human Resources Committee of the Board of Directors of the Company or its delegates (the “Committee”) has determined that Optionee shall be granted an option under the Plan as hereinafter set forth; The parties hereby agree that the Company grants, effective as of the Grant Date, Optionee a [Nonstatutory Stock Option] [Incentive Stock Option] (this “Option”) to purchase [SHARES] shares of its $0.001 par value Common Stock (the “Shares”) upon the terms and conditions set forth in this Agreement. 1. Plan Award. This Option is granted under and pursuant to the Plan and is subject to each and all of the provisions thereof. If this Option is

designated as an Incentive Stock Option, it is intended to qualify as an Incentive Stock Option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and to the extent this Option does not qualify as an Incentive Stock Option under Applicable Laws, then it is intended to be and will be treated as a Nonstatutory Stock Option. Notwithstanding the above, in the event that this Option is designated as an Incentive Stock Option and the Shares subject to this Option (and all other Incentive Stock Options granted to Optionee by the Company or any Subsidiary, including under other plans of the Company or any Subsidiary) that first become exercisable in any calendar year have an aggregate fair market value (determined for each Share as of the date of grant of the option covering such Share) in excess of $100,000, this Option shall be treated as a Nonstatutory Stock Option, in accordance with Section 9(b) of the Plan. 2. Exercise Price. The exercise price applicable to this Option (meaning, the price Optionee must pay in order to purchase any Shares hereunder) shall be [PRICE] per Share. 3. Vesting and Exercise of Option. Subject to Optionee’s not experiencing a Termination of Employment during the following vesting period, Optionee shall vest in and earn the right to exercise this Option on the following schedule: [VESTING SCHEDULE] 1

Processed and formatted by SEC Watch - Visit SECWatch.com

4. Expiration. This Option will expire ten (10) years from the Grant Date, unless sooner terminated or canceled in accordance with the provisions of the Plan. This means that (subject to the continuing service requirement set forth in Section 3 above and subject to earlier termination upon certain other events as set forth in the Plan) this Option must be exercised, if at all, on or before [EXPIRE DATE] (the “Expiration Date”). If this Option expires on a stock exchange holiday or weekend day, this Option will expire on the last trading day prior to the holiday or weekend. Optionee shall be solely responsible for exercising this Option, if at all, prior to its Expiration Date. The Company shall have no obligation to notify Optionee of this Option’s expiration. 5. Exercise Mechanics. This Option may be exercised by delivering to the Stock Plan Administrator at the Company’s head office a written or electronic notice stating the number of Shares as to which the Option is exercised or by any other method the Committee has approved. The notice must be accompanied by the payment of the full Option exercise price of such Shares. Exercise shall not be deemed to have occurred unless and until Optionee has delivered to the Company (or its authorized representative) an approved notice of exercise, full payment of the exercise price for the Shares being exercised and payment of any applicable withholding taxes in accordance with Section 8 below. Payment of the Option exercise price may be (a) in cash (including check or wire transfer); (b) through an approved cashless-brokered exercise program; (c) with other shares of the Company’s Common Stock held by Optionee which have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which this Option is being exercised (subject to the Company’s discretion to withhold approval for such payment method at any time); or (d) any combination of the foregoing methods of payment. 6. Termination of Employment. All rights of Optionee in this Option, to the extent that it has not previously become vested and been exercised, shall terminate upon Optionee’s Termination of Employment except as set forth in this Section 6. The portion of the Option that relates to any Shares that were unvested and unexercisable as of the date of Optionee’s Termination of Employment shall terminate and expire effective immediately upon such date. With respect to the vested and exercisable portion of the Option, and subject to the final sentence of this Section 6: (i) In the event of Termination of Employment other than as a result of Optionee’s death or disability and other than as a result of Cause, Optionee shall have three (3) months from the date of such Termination of Employment to exercise the Option as to the Shares subject to the Option that were vested and exercisable as of the date of Termination of Employment; provided that if during any part of such three (3) month period, the Option is not exercisable because the issuance of the Shares would violate Applicable Laws, the Option shall remain exercisable until thirty (30) days after the date the Optionee is notified by the Company that the Option is exercisable; provided further that if during any part of such three month period, a sale of the Shares would subject the Optionee to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earlier to occur of the tenth (10th ) day following the date on which a sale of the Shares by the Optionee would no longer be subject to suit and the one hundred ninetieth (190th ) day after the Optionee’s Termination of Employment; 2

(ii) In the event of Termination of Employment as a result of Optionee’s disability (including a Total and Permanent Disability), Optionee shall have twelve (12) months to exercise the Option as to the Shares subject to the Option that were vested and exercisable as of the date of Termination of Employment; (iii) In the event of Termination of Employment as a result of Optionee’s death or in the event of Optionee’s death within three (3) months following Optionee’s Termination of Employment, Optionee shall have twelve (12) months following the Optionee’s death to exercise the Option as to the Shares subject to the Option that were vested and exercisable as of the date of death or, if earlier, the date of Termination of Employment; and Notwithstanding the above, in no event may an Option be exercised, even as to vested and otherwise exercisable Shares, after the Expiration Date set forth in Section 4 above. 7. Transferability. This Option generally is not transferable by Optionee otherwise than by will or the laws of descent and distribution, and is exercisable only by Optionee during Optionee’s lifetime; provided however that if this Option is a Nonstatutory Stock Option, this Option may be transferred by instrument to an inter vivos or testamentary trust in which the Option is to be passed to beneficiaries upon the death of the trustor (settlor) or by gift or pursuant to domestic relations orders to family members of the Optionee. 8. Tax Matters. (i) Optionee is responsible for, and by accepting this Option agrees to bear, all taxes of any nature, including withholding taxes, interest or penalties arising out of the grant of this Option, the vesting or exercise of this Option or the subsequent sale of the Shares acquired pursuant to the exercise of this Option, or any violation of Code Section 409A that impacts this Option, that are legally imposed upon Optionee in connection with this Option, and the Company does not assume, and will not be liable to any party for, any cost or liability arising in connection with such tax liability legally imposed on Optionee. The Company has not provided any tax advice with respect to this Option or the disposition of the Shares. Optionee should obtain advice from an appropriate independent professional adviser with respect to the taxation implications of any aspect of this Option, including the grant, vesting or exercise of this Option or the subsequent sale of any Shares. (ii) In the event that the Company or the Employee’s employer, including any Affiliate or Subsidiary qualified to deduct tax at source (the “Employer”), is required to withhold any amount (including in connection with income tax, employment or payroll taxes, social security contributions or other similar amounts, with such obligation in aggregate referred to herein as the “Withholding Obligation”) as a result of any event occurring in connection with this Option, the Employee shall make a cash payment to the Company as necessary to cover all applicable Withholding Obligations at or prior to the time the event giving rise to the Withholding Obligation occurs; provided that (a) the Company has the right to withhold a portion of the Shares otherwise to be delivered upon exercise of this Option having a Fair Market Value equal to the amount of the Withholding Obligation in accordance with such rules as the Company may from time to time establish, (b) the Company or the Employer has the right, and 3

the Employee in accepting this grant explicitly authorizes the Company, to deduct an amount equal to the Withholding Obligation from the Employee’s compensation or (c) the Company may establish alternative procedures to ensure satisfaction of all applicable Withholding Obligations arising in connection with this Option. The Employee will receive a cash refund for any payment of cash or fraction of a surrendered share not necessary to satisfy the Withholding Obligations. (iii) Optionee acknowledges and agrees that the ultimate liability for any tax-related item legally due by Optionee is and remains Optionee’s responsibility and that the Company and or the Employer (a) make no representations nor undertakings regarding the treatment of any such tax items in connection with any aspect of this Option, including the grant, vesting or exercise of this Option or the subsequent sale of the Shares acquired upon exercise of this Option; and (b) do not commit to structure the terms or any aspect of this Option to reduce or eliminate the Employee’s liability for such tax items. The Company may refuse to honor the exercise of this Option and refuse to deliver the Shares if Optionee fails to comply with Optionee’s obligations in connection with the satisfaction of the Withholding Obligations. 9. Optionee Acknowledgements. By accepting the grant of this Option, Optionee acknowledges and agrees that the Plan is established voluntarily by the Company, it is discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time unless otherwise provided in the Plan or this Agreement. Optionee acknowledges that all decisions with respect to future grants, if any, will be at the sole discretion of the Company. Optionee’s participation in the Plan shall not create a right to further employment with Employer and shall not interfere with the ability of Employer to terminate Optionee’s employment relationship at any time with or without cause and it is expressly agreed and understood that employment is terminable at the will of either party, insofar as permitted by law. Optionee agrees that this Option is not part of normal or expected compensation or salary for any purposes, including, but not limited to calculating any severance, resignation, termination, redundancy, end-of-service payments, bonuses, long-service awards, pension or retirement benefits or similar payments insofar as permitted by law. In the event that Optionee is not an employee of the Company, this Option grant will not be interpreted to form an employment contract or relationship with the Company, the Employer or any Subsidiary or Affiliate of the Company. Optionee acknowledges that the future value of the underlying Shares is unknown, may increase or decrease in the future, and cannot be predicted with certainty. In consideration of the grant of this Option, no claim or entitlement to compensation or damages shall arise from termination of this Option or diminution in value of this Option or Shares purchased through exercise of this Option resulting from Optionee’s Termination of Employment by the Company or the Employer (for any reason whatsoever and whether or not in breach of Applicable Laws). 10. Data Transfer. Optionee explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Optionee’s personal data as described in this document by and among, as applicable, the Employer, and the Company and its Subsidiaries and Affiliates for the exclusive purpose of implementing, administering and managing Optionee’s participation in the Plan. Optionee understands that the Company, its Affiliates, its Subsidiaries and the Employer hold certain personal information about Optionee, including, but not limited to, name, home address and telephone number, date of birth, social security number (or other 4

identification number), salary, nationality, job title, any shares of stock or directorships held in the Company, details of all options or any other entitlement to shares of stock awarded, canceled, purchased, exercised, vested, unvested or outstanding in Optionee’s favor for the purpose of implementing, managing and administering the Plan (“Data”). Optionee understands that the Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in Optionee’s country or elsewhere and that the recipient country may have different data privacy laws and protections than Optionee’s country. Optionee may request a list with the names and addresses of any potential recipients of the Data by contacting the [Stock Plan Administrator]. Optionee authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing Optionee’s participation in the Plan, including any requisite transfer of such Data, as may be required to a broker or other third party with whom Optionee may elect to deposit any Shares acquired upon the exercise of this Option. Optionee understands that Data will be held only as long as is necessary to implement, administer and manage participation in the Plan. Optionee may, at any time, view Data, request additional information about the storage and processing of the Data, require any necessary amendments to the Data or refuse or withdraw the consents herein, in any case without cost, by contacting the Stock Plan Administrator in writing.

The Restricted Stock Units relate on a one-for-one basis to shares of the Company’s Common Stock (each such share, adjusted in accordance with Section 14 of the Plan, a “Share”). 2.

Distribution of Shares and Settlement of Award. Subject to any limitations set forth in this Agreement (including Sections 6 and 16) and the Plan, a number of Shares of Common Stock will be issued (“distributed”) to the Employee in settlement and full satisfaction of this Restricted Stock Unit equal to the number of Restricted Stock Units on (or as soon as practicable after, but in no later event later than the date that is forty-five (45) days after) the earlier of (a) the fourth anniversary of the Grant Date (the “Fourth Anniversary”), (b) the date of the Employee’s death prior to the Fourth Anniversary, or (c) the date of any accelerated distribution as a result of Section 4 below (such date, the “Change of Control Date”) (the earlier of such dates, the “Distribution Date”).

4. Change in Control. In the event of a Change in Control (as defined in the Plan and as modified by Section 16 below), the successor to the Company shall assume, or substitute equivalent awards for, this award on the same terms and conditions (including vesting conditions). The medium of settlement, whether shares, cash or some combination thereof, shall be determined at the discretion of the Administrator with the consent of the successor at the time of the Change in Control. If the award holder is involuntarily terminated for any reason other than award holder’s failure to substantially perform the duties of award holder’s position, after written notice and a reasonable opportunity to cure, within a two-year period beginning on the date of the Change in Control, all awards shall be vested and settled on the date of termination. For this purpose, involuntary termination shall include the occurrence of one or more of the following events (which occurs involuntarily to the award holder) provided that the award holder provides notice of such event within 30 days of its first occurrence and terminates employment within 12 months of the first occurrence of the event: (1) A material diminution in the award holder’s base compensation. (2) A material diminution in the award holder’s authority, duties, or responsibilities. (3) A material diminution in the authority, duties, or responsibilities of the supervisor to whom the award holder is required to report.

Dividends. To the extent the Company pays any cash dividends, stock dividends or other distributions on or with respect to Shares prior to the Distribution Date, the Employee shall be entitled to receive credit for cash dividends, stock dividends and other distributions paid during the Restricted Period with respect to the corresponding number of Shares of Common Stock underlying the Restricted Stock Units, provided that the fair market value of any such dividends or distributions shall be converted into an additional number of Restricted Stock Units (based on the Fair Market Value of the Common Stock at the time of such payment or distribution), which additional Restricted Stock Units shall be subject to the same forfeiture restrictions and restrictions on transferability as apply to, and shall be settled at the same time the Restricted Stock Units with respect to which they relate. Credit under this paragraph for any dividends paid during the Restricted Period shall be done as soon as practicable following the payment date for such dividend. 6. Tax Withholding Obligations. To meet the obligations of the Company (or a Subsidiary if the Employee is employed by an entity other than the Company) and the Employee with respect to any income or employment withholding taxes, FICA contributions, or the like under any federal, state, local or foreign statute, ordinance, rule, or regulation in or connection with the award grant, vesting or settlement of the Restricted Stock Units (including without limitation additional Restricted Stock Units (if any) provided to the Employee pursuant to Section 5 above), the Committee shall require that the Company withhold a number of shares of Common Stock otherwise deliverable under this award having a Fair Market Value sufficient to satisfy the statutory minimum (or such higher amount as is allowable without adverse accounting consequences) of the Employees estimated total federal, state, local and/or foreign tax obligations associated with grant, vesting or settlement of the Restricted Stock Units. The Company may also in lieu of or in addition to the foregoing, at its sole discretion, either require the Employee to deposit with the Company an amount of cash sufficient to meet such obligations and/or, withhold the required amounts from the Employee’s pay during the pay periods 2

immediately preceding the date on which any such applicable withholding tax or similar obligation otherwise arises. The Company shall not deliver any of the Certificates until and unless the Employee has made the deposit required herein or proper provision for all applicable tax withholding and similar obligations has been made. The Employee hereby consents to any action reasonably taken by the Company to meet all or any of such obligations. The Employee understands that, because this award is fully vested at grant, certain withholding taxes will be due immediately upon grant of the Restricted Stock Units. 7. Restriction on Transferability. Until the Distribution Date, the Restricted Stock Units may not be sold, transferred, pledged, assigned, or otherwise alienated at any time. Any attempt to do so contrary to the provisions hereof shall be null and void. Notwithstanding the above, distribution can be made pursuant to will, the laws of descent and distribution, intra-family transfer instruments or to an inter vivos trust. 8. Rights as Shareholder. Subject to Section 5 above with respect to dividend rights, the Employee shall not have voting or any other rights as a stockholder of the Company with respect to the Restricted Stock Units prior to the Distribution Date. Upon the Distribution Date, the Employee will obtain full voting and other rights as a shareholder of the Company. 9. Administration. The Committee shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and determinations made by the Committee shall be final and binding upon the Employee, the Company, and all other interested persons. No member of the Committee shall be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan or this Agreement. 10. Effect on Other Employee Benefit Plans. The value of the Restricted Stock Units granted pursuant to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating the Employee’s benefits under any employee or other benefit plan sponsored by the Company or any Subsidiary except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Subsidiary’s employee benefit plans. 11. No Right to Employment. The award of the Restricted Stock Units pursuant to this Agreement shall not give the Employee any right to remain employed by the Company or a Subsidiary or otherwise change the at-will nature of the Employee’s relationship with the Company or a Subsidiary, as applicable. It does not constitute part of the Employee’s salary or wages and, unless specifically agreed to otherwise in writing with the Company, is not relevant for purposes of determining any post-employment payment or severance to which the Employee may become entitled. 12. Amendment. This Agreement may be amended only by a writing executed by the Company and the Employee which specifically states that it is amending this Agreement. Notwithstanding the foregoing, this Agreement may be amended solely by the Committee by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to the Employee, and provided that no such amendment adversely 3

affects the rights of the Employee (but limiting the foregoing, the Committee reserves the right to change, by written notice to the Employee, the provisions of the Restricted Stock Units or this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change shall be applicable only to Restricted Stock Units which are then subject to restrictions as provided herein). Notwithstanding anything else to the contrary in this Section 12 or in the Plan, any amendment to this Agreement shall be subject to the requirements of Section 16 below. 13. Notices. Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of its stock administrator. Any notice to be given to Employee shall be addressed to Employee at the address listed in the Company’s records. By a notice given pursuant to this Section, either party may designate a different address for notices. Any notice shall have been deemed given when actually delivered. 14. Severability. If all or any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 15. Construction. The Restricted Stock Units are being issued pursuant to Section 11 of the Plan and are subject to the terms of the Plan. A copy of the Plan has been given to the Employee, and additional copies of the Plan are available upon request during normal business hours at the principal executive offices of the Company. To the extent that any provision of this Agreement violates or is inconsistent with an express provision of the Plan, the Plan provision shall govern and any inconsistent provision in this Agreement shall be of no force or effect. 16. Code Section 409A Matters. This Restricted Stock Unit award is a “nonqualified deferred compensation arrangement” subject to Code Section 409A. The Company has attempted in good faith to structure this Restricted Stock Unit award in a manner that conforms to the requirements of Code Section 409A(a)(2), (3) and (4) and any ambiguities herein will be interpreted to so conform with these requirements to the maximum extent permissible. To the extent the IRS challenges whether this award in fact complies with Code Section 409A(a)(2), (3) and (4), the Employee shall be fully responsible for any additional taxes, penalties and/or interest that might apply as a result of any adverse determination resulting from such challenge. Any subsequent deferral election, if permitted in the Company’s sole discretion, shall comply with the subsequent deferral election rules of Code Section 409A(a)(4)(C). Notwithstanding anything else to the contrary in this Agreement or in the Plan, the Company may accelerate distribution of Shares under this Agreement only in accordance with Treas. Reg. §1.409A-3(j)(4). Notwithstanding anything to the contrary contained in the Plan or this Agreement, any acceleration of the Distribution Date that occurs pursuant to Section 4 above and/or Section 14(c) of the Plan shall only occur on a Change in Control (as defined in the Plan) that qualifies as a “change in ownership or effective control,” or a “change in ownership of a substantial portion of the assets,” of the Company, all as defined under Code Section 409A. 4

In addition, and notwithstanding any provision of this Agreement including Section 3 above to the contrary, if at the time of the Employee’s Termination Date he or she is a “specified employee” (as defined in Code Section 409A), and if and only if the deferral of payment (distribution of Shares) as a result of the Employee’s termination of service is necessary in order to prevent any accelerated income recognition or additional tax under Code Section 409A(a)(1), then the Distribution Date shall be delayed until the earlier of (1) that date that is six months following the date on which occurs the Employee’s separation from service or (2) the date of the Employee’s death following his or her separation from service. 17. Miscellaneous. (a) The Board may terminate, amend, or modify the Plan; provided, however, that no such termination, amendment, or modification of the Plan may in any way adversely affect the Employee’s rights under this Agreement, without the Employee’s written approval. (b) This Agreement shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. The Company shall have no liability for failure to issue Shares pursuant to this Agreement unless it is able to do so in compliance with all Applicable Laws. (c) All obligations of the Company under the Plan and this Agreement, with respect to the Restricted Stock Units, shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. (d) By signing this Agreement, the Employee acknowledges that his or her personal employment or other service information regarding participation in the Plan and information necessary to determine and pay, if applicable, benefits under the Plan must be shared with other entities, including companies related to the Company and persons responsible for certain acts in the administration of the Plan. By signing this Agreement, the Employee consents to such transmission of personal data, as the Company believes is appropriate to administer the Plan. (e) To the extent not preempted by federal law, this Agreement shall be governed by, and construed in accordance with, the laws of the State of California. 5

IN WITNESS WHEREOF, the parties have executed and delivered this Agreement effective as of the day and year first above written. “Employee”

“Company” Exponent, Inc. By Name: Richard L. Schlenker, Jr. Title: Chief Financial Officer and Corporate Secretary 7 Exhibit 10.33 EXPONENT, INC. 2008 Equity Incentive Plan Restricted Stock Unit Director Grant Agreement

This Restricted Stock Unit Director Grant Agreement (the “Agreement”) is entered into between Exponent, Inc., a Delaware corporation (the “Company”), and (the “Director”). Pursuant to the terms of the 2008 Equity Incentive Plan (the “Plan”) the Company hereby awards to Director restricted stock units (“Restricted Stock Units”) on the terms and conditions as set forth in this Agreement and the Plan. The grant date for this award is 200 (the “Grant Date”). Capitalized terms used but not defined in this Agreement shall have the meaning specified in the Plan.

,

In consideration of the mutual promises set forth below, the parties hereto agree as follows: 1. Award of Restricted Stock Units. Subject to the terms and conditions of this Agreement and the Plan (the terms of which are incorporated herein by reference) and effective as of the Grant Date, the Company hereby grants to the Director Restricted Stock Units. The Restricted Stock Units relate on a one-for-one basis to shares of the Company’s Common Stock (each such share, adjusted in accordance with Section 14 of the Plan, a “Share”). 2. Vesting. Restricted Stock Units vest (meaning that the Director’s right to the Restricted Stock Units become nonforfeitable and no longer subject to any service requirement) in three equal installments on the day prior to each of the Company’s three annual stockholder meetings next following the Grant Date (each such date, a “Vesting Date”), provided that with respect to each Vesting Date the Director remains in continuous service on the Company’s Board of Directors (the “Board”) from the Grant Date through the Vesting Date. The period between the Grant Date and the earlier of (a) the third Vesting Date referred to in the preceding sentence (b) the Termination Date (defined in Section 3 below), and (c) the date of any accelerated vesting pursuant to Section 5 below (such date, the “Change in Control Date”) is referred to as the “Restricted Period.” 3. Effect of Termination of Service; Forfeiture. If the Director’s service as a member of the Board terminates for any reason or under any circumstances (including death or disability), the Director will vest in a pro rata portion of the Restricted Stock Units through the date of such service termination that qualifies as a “separation from service” with respect to Board service under Code Section 409A (the “Termination Date”) so that he or she will be treated as vested in that number of Restricted Stock Units that vested on each Vesting Date occurring prior to the Termination Date plus that additional number of Restricted Stock Units as he or she would have been vested in as of the Termination Date if the award had been subject to daily vesting for the 365-day period beginning on the last preceding Vesting Date and ending on the Termination

Date and the remainder of the Restricted Stock Units shall be forfeited. Upon forfeiture of Restricted Stock Units, the portion of the award so forfeited shall terminate and the Company shall have no obligation to issue any Shares in settlement of that portion of the award. 4. Distribution. Subject to any limitations set forth in this Agreement (including Sections 8 and 17) and the Plan, and subject to any deferral election made pursuant to Section 6 below, a number of Shares of Common Stock will be issued (“distributed”) to the Director in settlement of this Restricted Stock Unit equal to the number of then-vested Restricted Stock Units on (or as soon as practicable after, but in no later event later than the date that is forty-five (45) days after) the earlier of (a) the third anniversary of the Grant Date, (b) the Termination Date, or (c) the Change in Control Date (the earlier of such dates, and without regard to any deferral of such date pursuant to Section 6, the “Distribution Date”). Subject to any deferral election made pursuant to Section 6 below, upon or as soon as practicable following the Distribution Date, stock certificates (including electronic representations of the same, the “Certificate”) evidencing the Shares issued upon settlement of vested Restricted Stock Units shall be issued and registered in the Director’s name and delivered to (or appropriate notice in the case of electronic Certificate delivered to) the Director (or in the case of the Director’s death, to the Director’s beneficiary or estate). 5. Change in Control. In the event of a Change in Control (as defined in the Plan and as modified by Section 17 below), all awards shall be vested and the shares underlying the Restricted Stock Units will be distributed as set forth in section 4 above. 6. Deferral Election. Subject to any conditions deemed appropriate from time to time by the Committee (including suspension of the right to elect deferrals or to make changes to any existing deferral election), the Director may elect to defer the Distribution Date set forth in Section 4 above using the form attached as Exhibit A (or any successor form approved by the Administrator). 7. Dividends. Participants holding Restricted Stock Units shall be entitled to receive credit for cash dividends, stock dividends and other distributions paid during the Restricted Period (or, with respect to an award as to which a further deferral election has been made under Section 6 above, also during the period following the Restricted Period prior to the date the Shares are to be distributed under the terms of such deferral election) with respect to the corresponding number of Shares of Common Stock underlying the Restricted Stock Units , provided that the fair market value of any such dividends or distributions shall be converted into an additional number of Restricted Stock Units (based on the Fair Market Value of the Common Stock at the time of such payment or distribution), which additional Restricted Stock Units shall be subject to the same forfeiture restrictions and restrictions on transferability as apply to, and shall be settled at the same time as, and subject to the same deferral elections as, the Restricted Stock Units with respect to which they relate. Credit under this paragraph for any dividends paid during the Restricted Period (including any additional deferral period) shall be done as soon as practicable following the payment date for such dividend. 8. Tax Withholding Obligations. In such rare circumstances in which withholding is applicable, to meet any such obligations of the Company and Director that might arise with respect to any withholding taxes, FICA contributions, or the like under any federal, state, or local 2

statute, ordinance, rule, or regulation in or connection with the award grant, vesting, deferral, or settlement of the Restricted Stock Units, the Committee can, in the limited circumstances where appropriate, require that the Company withhold a number of shares of Common Stock otherwise deliverable having a Fair Market Value sufficient to satisfy the statutory minimum (or such higher amount as is allowable without adverse accounting consequences) of the Participant’s estimated total federal, state, and local tax obligations associated with vesting or settlement of the Restricted Stock Units. In such rare circumstances, the Company may also, in lieu of or in addition to the foregoing, at its sole discretion, either require the Director to deposit with the Company an amount of cash sufficient to meet the withholding requirements and/or withhold the required amounts from the Director’s pay during the pay periods next following the date on which any such applicable tax liability otherwise arises. The Company shall not deliver any of the Certificates until and unless the Director has made the deposit required herein or proper provision for required withholding has been made. The Director hereby consents to any action reasonably taken by the Company to meet the withholding obligations. 9. Restriction on Transferability. Until the Distribution Date, the Restricted Stock Units may not be sold, transferred, pledged, assigned, or otherwise alienated at any time. Any attempt to do so contrary to the provisions hereof shall be null and void. 10. Rights as Shareholder. Subject to Section 6 above with respect to dividend rights, the Director shall not have voting or any other rights as a stockholder of the Company with respect to the Restricted Stock Units prior to the Distribution Date. Upon the Distribution Date, the Director will obtain full voting and other rights as a shareholder of the Company. 11. Administration. The Committee shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and determinations made by the Committee shall be final and binding upon the Director, the Company, and all other interested persons. No member of the Committee shall be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan or this Agreement. 12. Effect on Other Employee Benefit Plans. The value of the Restricted Stock Units granted pursuant to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating the Director’s benefits under any director or other benefit plan sponsored by the Company or any Subsidiary except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Subsidiary’s employee benefit plans. 13. Amendment. This Agreement may be amended only by a writing executed by the Company and the Director which specifically states that it is amending this Agreement. Notwithstanding the foregoing, this Agreement may be amended solely by the Committee by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to the Director, and provided that no such amendment adversely affects the rights of the Director (but limiting the foregoing, the Committee reserves the right to change, by written notice to the Director, the provisions of the Restricted Stock Units or this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of 3

any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change shall be applicable only to Restricted Stock Units which are then subject to restrictions as provided herein). Notwithstanding anything else to the contrary in this Section 13 or in the Plan, any amendment to this Agreement shall be subject to the requirements of Section 17 below. 14. Notices. Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of its stock administrator. Any notice to be given to Director shall be addressed to Director at the address listed in the Company’s records. By a notice given pursuant to this Section, either party may designate a different address for notices. Any notice shall have been deemed given when actually delivered. 15. Severability. If all or any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 16. Construction. The Restricted Stock Units are being issued pursuant to Section 11 of the Plan and are subject to the terms of the Plan. A copy of the Plan has been given to the Director, and additional copies of the Plan are available upon request during normal business hours at the principal executive offices of the Company. To the extent that any provision of this Agreement violates or is inconsistent with an express provision of the Plan, the Plan provision shall govern and any inconsistent provision in this Agreement shall be of no force or effect. 17. Code Section 409A Matters. This Restricted Stock Unit award is a nonqualified deferred compensation arrangement subject to Code Section 409A. The Company has attempted in good faith to structure this Restricted Stock Unit award (including any deferral elections made in connection with such award) in a manner that conforms to the requirements of Code Section 409A(a)(2), (3) and (4) and any ambiguities herein will be interpreted to so conform with these requirements to the maximum extent permissible. To the extent the IRS challenges whether this award in fact conforms with Code Section 409A(a)(2), (3) and (4), the Director shall be fully responsible for any additional taxes, penalties and/or interest that might apply as a result of any adverse determination resulting from such challenge. To the extent this award contemplates multiple Distribution Dates (including as a result of a deferral election), each amount to be paid (Shares to be distributed) hereunder on any particular Distribution Date is designated as a separate payment and such payments will not collectively be treated as a single payment. Any subsequent deferral election shall comply with the subsequent deferral election rules of Section 409A(a)(4)(C) (which, as relevant to this award, are set forth on the election form attached hereto as Exhibit A). Notwithstanding anything else to the contrary in this Agreement or in the Plan, the Company may accelerate distribution of Shares under this Agreement only in accordance with Treas. Reg. §1.409A-3(j)(4). Notwithstanding anything to the contrary contained in the Plan or this Agreement, any acceleration of the Distribution Date that occurs pursuant to Section 5 above and/or Section 14(c) of the Plan shall only occur on a Change in Control (as defined in the Plan) that qualifies as a 4

“change in ownership or effective control,” or a “change in ownership of a substantial portion of the assets,” of the Company, all as defined under Code Section 409A. In addition, for all purposes under this Agreement and to the extent permitted under Code Section 409A, the Director shall have a “separation from service” as defined under Code Section 409A upon the Termination Date. In addition, and notwithstanding any provision of this Agreement including Section 4 above to the contrary, if at the time of the Director’s Termination Date he or she is a “specified employee” (as defined in Code Section 409A), and if and only if the deferral of payment (distribution of Shares) as a result of the Director’s termination of service is necessary in order to prevent any accelerated income recognition or additional tax under Code Section 409A(a)(1), then the Distribution Date shall be delayed until the earlier of (1) that date that is six months following the date on which occurs the Director’s separation from service or (2) the date of the Director’s death following his or her separation from service. 18. Miscellaneous. (a) The Board may terminate, amend, or modify the Plan; provided, however, that no such termination, amendment, or modification of the Plan may in any way adversely affect the Participant’s rights under this Agreement, without the Participant’s written approval. (b) This Agreement shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. The Company shall have no liability for failure to issue Shares pursuant to this Agreement unless it is able to do so in compliance with all Applicable Laws. (c) All obligations of the Company under the Plan and this Agreement, with respect to the Restricted Stock Units, shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. (d) By signing this Agreement, the Director acknowledges that his or her personal employment or other service information regarding participation in the Plan and information necessary to determine and pay, if applicable, benefits under the Plan must be shared with other entities, including companies related to the Company and persons responsible for certain acts in the administration of the Plan. By signing this Agreement, the Director consents to such transmission of personal data, as the Company believes is appropriate to administer the Plan. (e) To the extent not preempted by federal law, this Agreement shall be governed by, and construed in accordance with, the laws of the State of California. 5

18. General Code Section 409A Matters. This award may be a “nonqualified deferred compensation arrangement” subject to Code Section 409A. To the extent that it is, the parties intend that it conform to the requirements of Code Section 409A(a)(2), (3) and (4) and any ambiguities herein will be interpreted to so conform with these requirements to the maximum extent permissible. To the extent the IRS challenges whether this award in fact conforms with Code Section 409A(a)(2), (3) and (4), the Employee shall be fully responsible for any additional taxes, penalties and/or interest that might apply as a result of any adverse determination resulting from such challenge. Any subsequent deferral election, if permitted in the Company’s sole discretion, shall comply with the subsequent deferral election rules of Code Section 409A(a)(4)(C).

Effect of Termination of Service or Leave of Absence. If the Employee’s service is terminated by the Employee or by the Company or a Subsidiary for any reason except Employee’s death, Disability or “Retirement” (termination after age 59 1/2 ) before the Vesting Date, all restricted stock units shall be forfeited.

In the case of death, Certificates shall be delivered to the Employee’s beneficiary or estate as soon as practicable following the date of death. 5. Dividends. Participants holding restricted stock units shall be entitled to receive cash payments equal to any cash dividends and other distributions paid with respect to a corresponding number of shares of Common Stock, provided that if any such dividends or distributions are paid in shares of Common Stock, the Fair Market Value of such shares of Common Stock shall be converted into restricted stock units, and further provided that such restricted stock units shall be subject to the same forfeiture restrictions and restrictions on transferability as apply to the Restricted Stock Units with respect to which they relate. 6. Tax Withholding Obligations. To meet the obligations of the Company and Employee with respect to any withholding taxes, FICA contributions, or the like under any federal, state, or local statute, ordinance, rule, or regulation in or connection with the award, deferral, or settlement of the restricted stock units, the Committee shall require that the Company withhold a number of shares of Common Stock otherwise deliverable having a Fair Market Value sufficient to satisfy the statutory minimum (or such higher amount as is allowable without adverse accounting consequences) of the Participant’s estimated total federal, state, and local tax obligations associated with vesting or settlement of the restricted stock units. The Company may also in lieu of or in addition to the foregoing, at its sole discretion, either require the Employee to deposit with the Company an amount of cash sufficient to meet the withholding requirements and/or, withhold the required amounts from the Employee’s pay during the pay periods next following the date on which any such applicable tax liability otherwise arises.

Employee hereby consents to any action reasonably taken by the Company to meet the withholding obligations. 7. Restriction on Transferability. Until distribution, the restricted stock units may not be sold, transferred, pledged, assigned, or otherwise alienated at any time. Any attempt to do so contrary to the provisions hereof shall be null and void. Notwithstanding the above, distribution can be made pursuant to will, the laws of descent and distribution, intra-family transfer instruments or to an inter vivos trust. 8. Rights as Shareholder. The Employee shall not have voting or any other rights as a shareholder of the Company with respect to the restricted stock units. Upon settlement of the restricted stock units into shares of Company Stock, the Employee will obtain full voting and other rights as a shareholder of the Company. 9. Administration. The Committee shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and determinations made by the Committee shall be final and binding upon the Employee, the Company, and all other interested persons.

10. Effect on Other Employee Benefit Plans. The value of the restricted stock units granted pursuant to this Agreement shall not be included as compensation, earnings, salaries, or other similar terms used when calculating the Employee’s benefits under any employee benefit plan sponsored by the Company or any Subsidiary except as such plan otherwise expressly provides. The Company expressly reserves its rights to amend, modify, or terminate any of the Company’s or any Subsidiary’s employee benefit plans. 11. No Employment Rights. The award of the restricted stock units pursuant to this Agreement shall not give the Employee any right to remain employed by the Company or a Subsidiary. Also, the award is completely within the discretion of the Company. It is not made as a part of any ongoing element of compensation or something which Employee should expect to receive annually or on any other periodic basis. It does not constitute part of Employee’s salary or wages and unless specifically agreed to otherwise with the Company is not relevant for purposes of determining any post-employment payment or severance. 12. Amendment. This Agreement may be amended only by a writing executed by the Company and the Employee which specifically states that it is amending this Agreement. Notwithstanding the foregoing, this Agreement may be amended solely by the Committee by a writing which specifically states that it is amending this Agreement, so long as a copy of such amendment is delivered to the Employee, and provided that no such amendment adversely affects the rights of the Employee (but limiting the foregoing, the Committee reserves the right to change, by written notice to the Employee, the provisions of the restricted stock units or this Agreement in any way it may deem necessary or advisable to carry out the purpose of the grant as a result of any change in applicable laws or regulations or any future law, regulation, ruling, or judicial decision, provided that any such change shall be applicable only to restricted stock units which are then subject to restrictions as provided herein). 13. Notices. Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of its stock administrator. Any notice to be given to Employee shall be addressed to Employee at the address listed in the Company’s records. By a notice given pursuant to this Section, either party may designate a different address for notices. Any notice shall have been deemed given when actually delivered. 14. Severability. If all or any part of this Agreement or the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any portion of this Agreement or the Plan not declared to be unlawful or invalid. Any Section of this Agreement (or part of such a Section) so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while remaining lawful and valid. 15. Construction. The restricted stock units are being issued pursuant to Section 7 of the Plan and are subject to the terms of the Plan. A copy of the Plan has been given to the Employee, and additional copies of the Plan are available upon request during normal business hours at the principal executive offices of the Company. To the extent that any provision of this Agreement violates or is inconsistent with an express provision of the Plan, the Plan provision shall govern and any inconsistent provision in this Agreement shall be of no force or effect. 3

16. Miscellaneous.

(b) This Agreement shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. (c) All obligations of the Company under the Plan and this Agreement, with respect to the restricted stock units, shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company. (d) By signing this Agreement, the Employee acknowledges that his or her personal employment information regarding participation in the Plan and information necessary to determine and pay, if applicable, benefits under the Plan must be shared with other entities, including companies related to the Company and persons responsible for certain acts in the administration of the Plan. By signing this Agreement employee consents to such transmission of personal data as the Company believes is appropriate to administer the Plan. (e) To the extent not preempted by federal law, this Agreement shall be governed by, and construed in accordance with, the laws of the State of California. (f) “Disability” means the total and permanent disability of the Employee where, by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months, the Participant is either (i) unable to engage in any substantial gainful activity; or (ii) receiving income replacement benefits for a period of not less than three (3) months under an accident or health plan covering employees of the Company, in each case in accordance with Code Section 409A and applicable guidance issued thereunder. (g) The only circumstance in which a transaction specified in Section 17 below will result in acceleration of distribution of Shares shall be in connection with a transaction or series of transactions in which the Company experiences a “change in ownership,” a “change in effective control,” or a “change in the ownership of a substantial portion of assets,” in each case as defined under Code Section 409A and applicable guidance issued thereunder. 17. Change in Control. In the event of a Change in Control, the successor to the Company shall assume, or substitute equivalent awards for, this award on the same terms and conditions (including vesting conditions). The medium of settlement, whether shares, cash or some combination thereof, shall be determined at the discretion of the Administrator with the consent of the successor at the time of the Change in Control. If the award holder is involuntarily terminated for any reason other than award holder’s failure to substantially perform the duties of award holder’s position, after written notice and a reasonable opportunity to cure, 4

Processed and formatted by SEC Watch - Visit SECWatch.com

within a two-year period beginning on the date of the Change in Control, all awards shall be vested and settled on the date of termination. For this purpose, involuntary termination shall include the occurrence of one or more of the following events (which occurs involuntarily to the award holder) provided that the award holder provides notice of such event within 30 days of its first occurrence and terminates employment within 12 months of the first occurrence of the event: (1) A material diminution in the award holder’s base compensation. (2) A material diminution in the award holder’s authority, duties, or responsibilities. (3) A material diminution in the authority, duties, or responsibilities of the supervisor to whom the award holder is required to report. (4) A material diminution in the budget over which the award holder retains authority. (5) A material change in the geographic location at which the award holder must perform the services. 18. General Code Section 409A Matters. This award may be a “nonqualified deferred compensation arrangement” subject to Code Section 409A. To the extent that it is, the parties intend that it conform to the requirements of Code Section 409A(a)(2), (3) and (4) and any ambiguities herein will be interpreted to so conform with these requirements to the maximum extent permissible. To the extent the IRS challenges whether this award in fact conforms with Code Section 409A(a)(2), (3) and (4), the Employee shall be fully responsible for any additional taxes, penalties and/or interest that might apply as a result of any adverse determination resulting from such challenge. Any subsequent deferral election, if permitted in the Company’s sole discretion, shall comply with the subsequent deferral election rules of Code Section 409A(a)(4)(C). In addition, notwithstanding anything else to the contrary in this Agreement or in the Plan, (a) the Company may accelerate distribution of Shares under this Agreement only in accordance with Treas. Reg. §1.409A-3(j)(4), and (b) no amendment may be made to this award except as permitted under this paragraph. In addition, if at the time of the Employee’s Termination Date he or she is a “specified employee” (as defined in Code Section 409A), and if and only if the deferral of payment or distribution of Shares as a result of the Employee’s termination of services is necessary in order to prevent any accelerated income recognition or additional tax under Code Section 409A(a)(1), then the Distribution Date shall be delayed until the earlier of (1) that date that is six months following the date on which occurs the Employee’s separation from service or (2) the date of the Employee’s death following his or her separation from service. 5

amount to be paid (Shares to be distributed) hereunder on any particular Distribution Date is designated as a separate payment and such payments will not collectively be treated as a single payment.

Reg. §1.409A-3(j)(4). In addition, and notwithstanding any provision of this Agreement including Section 4 above to the contrary, if at the time of the Director’s Termination Date he or she is a “specified employee” (as defined in Code Section 409A), and if and only if the deferral of payment or distribution of Shares as a result of the Director’s termination of services is necessary in order to prevent any accelerated income recognition or additional tax under Code Section 409A(a)(1), then the Distribution Date shall be delayed until the earlier of (1) that date that is six months following the date on which occurs the Director’s separation from service or (2) the date of the Director’s death following his or her separation from service.
